  Chapter 389 Top Journals (First Update)

   After collecting the final data, Lu Chen returned to the bedroom.

  The procedure of clinical research is simple, collecting data, processing and analyzing data, drawing conclusions, and finally writing a paper.

   At present, Lu Chen has only completed the first step.

   But this first step is also the most important step, accounting for more than 50% of the overall workload.

   "Ke Yue, thank you and your roommate for your help during this time." Lu Chen sent Ke Yue a WeChat message.

  Ke Yue immediately replied: "If there is anything in the paper after that, you have to tell me, I can help."

"OK."

   However, Ke Yue's help is not needed for the next thing.

  Data processing and analysis mainly uses SPSS software, which Lu Chen can handle by himself.

  …

   In the next week, Lu Chen focused more on data processing.

   On weekends, Lu Chen stayed in the bedroom as usual,

   "Lu Chen, I heard that there is a very powerful person in your Cardiology Department." Zhou Wei, who was moving bricks in the laboratory, sent him a WeChat message, "As soon as the research was conducted, an SCI of one work was published!"

   "Well, it's still from the eight districts in our hearts." Lu Chen replied, "What, want to meet? I can introduce you."

   "Hey, forget it." Zhou Wei said, "Let me tell you, my recent paper has also been accepted! Although it's not the first work, the score is not bad, with 3 points!"

   "You're not bad boy." Lu Chen praised.

   A paper can have many authors.

   But generally, only the corresponding author and the first author are acknowledged.

   Corresponding author, usually a mentor, is the proposer of the idea of ​​the article.

  The first author is the main experimenter, or the author of the paper.

   The remaining second, third, and fourth authors all contributed to the paper, such as Ke Yue, who helped with data processing and so on.

   Generally speaking, any evaluation, advance evaluation, or promotion, only the papers of the corresponding author and the first author will be recognized.

However, if the score of a SCI paper is very high, such as Nature, Science, etc., the impact factor score is above 100%, as long as you leave your name in the author of the paper, no matter which author, then you can almost be in a third-rate University professor.

"Oh, I did this experiment with my brother." Zhou Wei said, "So the tutor is the communication, and the brother is the first one, so he gave me a second one. The idea of ​​the next experiment is what I thought of myself. If I can make it, it is absolutely It's all done!"

   "Then I'll wait for your good news." Lu Chen said.

   "You too, let's encourage each other." Zhou Wei said.

   Everyone around here is working hard!

  Lu Chen closed WeChat and continued processing the data in hand.

   His data processing, with the support of the clinical research skill card and the statistical skill card, used a number of statistical methods.

  It includes Kaplan-Merier method, Log-rank method, multivariate COX regression analysis and so on.

  Using a variety of statistical methods to repeatedly process the experimental data, the final conclusion can be more convincing!

   When Wang Zihao passed by Lu Chen, he accidentally caught a glimpse of his computer screen and was almost stunned.

   The operator symbols on the screen made him dazzled.

   "Lu Chen, how many statistical methods did you use?" Wang Zihao couldn't help asking.

"Not many, just five." Lu Chen said, "First use the chi-square test and Fisher's exact probability method for comparison, then use the Kaplan-Merier method to analyze, and then use the Log-rank method to calculate whether there is a statistical difference, and finally use the more A variable COX regression analysis confirmed my conclusions."

   Wang Zihao: "..."

   Damn Versailles!

   He only used a chi-square test, Lu Chen actually used so many methods.

  The difference is really quite big...

   "Lu Chen, did you all do statistics by yourself? Didn't you ask your classmates majoring in statistics to help you do it?" Wang Zihao suddenly thought of this.

  Statistics is a brand new profession!

  Where did Lu Chen get so much energy to learn statistics?

   "Well, it's better to rely on yourself. It's impossible to rely on others to help us with statistics every time, right?" Lu Chen smiled.

   "You're so good!" Wang Zihao gave Lu Chen a thumbs up.

   This requires him to learn. He thinks he has no patience or ability.

  Looking at Lu Chen's concentration, Wang Zihao sighed slightly.

  Lu Chen's current achievements are inseparable from his hard work!

   He hadn't seen it until now. Lu Chen went out to play during the weekend break.

   This can also explain why his sister Wang Ruoxi has a good impression of Lu Chen.

   However, Lu Chen, a straight man, doesn't understand style.

   Wang Zihao felt a little pity, and heaved a sigh of relief.

  Unfortunately, it's because Lu Chen's people are really good. He's been with him for so long, and he's definitely a reliable man.

   breathed a sigh of relief, because if the two of them did, wouldn't Lu Chen become his brother-in-law?

  We meet every day, and we have to call "brother-in-law"?

  …

  Lu Chen didn't know Wang Zihao behind him, he was thinking about his own affairs in a mess.

   He is still busy with data processing.

   Now comes the final step of data processing!

   is to see if the conclusions drawn are statistically significant!

   "This last step, we can see the difference!"

  Lu Chen was a little nervous in his heart.

  If there is no statistical significance, then his hard work in the past few months will be in vain!

   Therefore, some experimenters often do not obtain satisfactory results in this last step, so they will change the data in order to obtain a positive result.

   This is also a very common phenomenon in China.

   Especially some hospitals in China.

   Blindly pursue papers, ignoring that many doctors have no scientific research ability at all, so what should we do?

   Only buy papers, falsify data, or even plagiarize!

   This is a very realistic and sad thing...

   "Di Di Di..."

  The computer was running, and several unknown characters flashed continuously.

  Finally, after waiting for five minutes, the computer screen outputs the final result

  P<0.05 - statistically significant!

   That is to say, in a small sample pilot study, dapagliflozin can prevent heart failure in the early stage of acute myocardial infarction, and this proposition is established.

  Lu Chen showed joy and sighed: Five months, finally completed! "

   Others have published several core journal papers in five months.

   And he is still a zero!

  …

  The data is processed, and the only thing left is to write the paper.

   Writing of the thesis, step by step.

   With data and conclusions, it is much simpler.

  Lu Chen completed the Chinese paper first, and then translated the Chinese into English.

  If you want to publish high-scoring SCI papers, Huaxia journals do not have such influence for the time being, only foreign journals do.

   Even the most authoritative Chinese journal series in China has limited international influence.

   This is also a very helpless reality!

  The four top journals in the field of medicine are all abroad.

   are NEJM (New England Journal of Medicine), The Lancet (Lancet), JAMA (American Medical Journal), TheBMJ (British Medical Journal).

  Lu Chen definitely doesn't dare to expect these four top journals now, but for his first paper, he must also find a more influential foreign journal.

   However, Lu Chen didn't know much about foreign journals, so he asked Senior Sister Sun Guoguo.

  Sister Guoguo Sun has been working hard in scientific research for many years, and she still knows a lot about the journals in the cardiovascular field.

   She immediately gave Lu Chen three suggestions.

   "CardiologyClinics, Cardiology, PediatricCardiology."

  Lu Chen looked up the relevant journal information.

  The impact factor is 1-2 points, no more than 3 points.

  Lu Chen frowned, this did not meet his expectations!
