@eslmaher @NIHRStatistics @JianhuaWu6 @QMUL @MK_statistics I'm very glad you enjoyed it. Thank you 🙏

@FerryDanini I'm so sad to miss it. I will be a km away but stuck in a meeting. Good luck! I hope it will be recorded

Very happy to present my work in English next week in London on phloroglucinol (a very common drug in France and some other countries), its shady history, the sexist bias among other things that led to its success and much more 👇

@ErwanLamy1 @BacheletPe @pierre_bat Cette vision romantique du métier est une des manières de l'exercer (cela convient à certains et justifie leur sentiment d'importance), mais il y a des alternatives valides plus productives et plus saines.

@BacheletPe @pierre_bat Rassurez-vous, personne ne va le suivre, et c'est bien le problème. Quant à vous, continuez à ne pas vous fatiguer à argumenter, je suis sûr que ça vous réussit.

@_MargaritaMB Fantastic news!!! Congratulations 🍾

Feeling super happy: Just promoted to full Prof!🙂

@Clara_Locher Bizarrement chez moi, ca ne marche pas avec Firefox, mais ca marche avec Microsoft Edge...

Bon, c'est pas dans la thématique du jour mais impossible de me connecter à Clinical Trials et je n'ai pas un début d'explication donc si quelqu'un a une idée, je prends.

Today, @MalhotraAnanya4 is in Amsterdam 🇳🇱 presenting results on how quality of life is affected following #immunotherapy as part of the @QualitopProject. Want to find out more? Check out the QUALITOP website 👇 bit.ly/45IBY3d

@FerryDanini It probably means that pedantic reviewers exist both in philosophy and history (and any other field) 😆

First time I got a reviewer complaining my writing style is not academic enough 🫣 I wonder if philosophers and historians write differently?

"Don’t be steamrollered by clinicians" Working life for some medical statisticians can feel like playing second fiddle, according to our latest free-to-read article: ow.ly/1ql250S6Mgz #statistics #freetoread

🖐A new #job opening for a 2-y position as a postdoc in my team! 🔺I'm considering only applications which include responses to the 3 questions I asked in the ad ;) So, read it before applying. 🙏 Help me circulate that job offer :) lih.lu/fr/job-fr/?val… @LIH_Luxembourg

I have several exciting openings for PhD students and postdocs in the context of my advanced ERC grant #ERCAdG on Assumption-lean (Causal) Modeling and Estimation. Please spread the news! users.ugent.be/~svsteela/ @DassGhent @UGent_fwe @ResearchUGent @UGent @ERC_Research

@SPilleron I don't see how this example illustrates selection bias. It seems to show what happens when we adjust on a mediator

Selection bias is an important problem often overlooked and reduced to “a limitation to the study »! It can be more than just a limitation of a study, it can reverse an association !

@Sonic_urticant All of the above

🧵 New Special Communication examines drawing causal inferences about the effects of interventions from observational studies in medical journals and suggests a framework that might be used. ja.ma/3UxeAjL

@NaudetFlorian @Foreman1David @IoanaA_Cristea And not aware as well that they wouldn't be a co-author on the paper?

@Foreman1David @IoanaA_Cristea From the online response to the reviewer we learn that this person was a student (response 1). And that this person was not aware nor of the hypothesis, nor of the aim of the study (response 2).

Twitter has focused mostly on a very glaring error of using the standard error in place of the standard deviation, but there are many other methodological problems in this recent meta-analysis of psilocybin for depression. bmj.com/content/385/bm…

Do you use inverse probability-of-treatment weights ⚖️ for causal inference? Wondering how variance can be estimated correctly🤔💭? Check out our new tutorial in Statistics in Medicine!👇 🔗bit.ly/3Uk34cK #epitwitter #causaltwitter @LSHTM @LSHTM_datastats

@FerryDanini cette "critique" illustre parfaitement pourquoi et par qui le spasfon est encore prescrit.

@LeyClem 😆en vrai j'ai trop rigolé

J'ai trouvé une critique de mon livre d'un médecin qui ne l'a clairement pas lu et qui se termine par cette phrase petite : "Bref, ce livre appartient à la face grise du wokisme et non sa face rose. Ne vous méprenez pas sur le titre" c'est trop drôle on dirait une parodie
