"We estimated 20% probability of detecting new treatments with OR > 50 …Increasing the number of RCTs from about 20 to 40 or 60 per year would double or triple the likelihood of detecting breakthrough treatments with dramatic effects.ā€œ

Wow. Only 1/5 of trials published in the last 10 years in major journals report patient involvement. Need to do much more here! bmj.com/content/389/bm…

Just 24 participants to go: Our Swisswide pragmatic #MultiSCRIPT trial is close to reaching 915 in about a year. Only possible through full embedding in routine care and with an outstanding team RC2NB and #SMC and the wonderful support of our patients. multiscript.rc2nb.ch

Breakthrough for #EBM! #GRADE, leading resource for certainty of evidence and evidence to recommendations now too complex, disorganized. Solution in 7 papers on GRADE essentials ā€œCore GRADEā€ in #BMJ. This week, introduction to series summarizes content. bmj.com/content/389/bm…

You can write clinical trial protocols meeting all formal requirements for regulators and ethic committees that produce zero scientific value. Thats a problem. Clinical study protocols are not primarily regulatory documents.

The GRADE approach is the dominant system of rating certainty of evidence and grading healthcare recommendations worldwide. This article introduces a series of papers on new guidance for the GRADE approach bmj.com/content/389/bm…

A major update to the CONSORT reporting guidance for clinical trials was published last week. šŸ“Œ CONSORT 2025 replaces all previous versions and should be used from now on. So what’s new and what’s different? 1/7 #MethodologyMonday #116 (COI - I am a co-author)

#GRADE, indeed #EBM, will never be the same. GRADE papers have become too complex and difficult to navigate. The remedy: a series of 7 papers in the #BMJ laying out the essentials of GRADE: Core GRADE. This week, an overview of Core GRADE. bmj.com/content/389/bm…

Excellent meta-research: A trial within a large trial shows that consent form length impacts recruitment. Please consider too much text can exclude vulnerable groups / We need to rethink consent forms, too much information may harm. jamanetwork.com/journals/jama/…

Thanks Lars G. Hemkens for the positive feedback on our recently published ā€˜RCT within a large RCT’. We need to randomize to understand how we can improve processes in our society.
