Almost all high-income countries have a national policy recommending shared decision-making before PSA screening. We show: a) this recommendation never justified by evidence; b) best evidence is PSA screening not a preference-sensitive decision. journals.sagepub.com/eprint/UP9VV...

Background Almost all national guidelines groups recommend that individual men make an informed personal decision about whether to be screened for prostate canc...

I've long been suspicious of "regret" as an endpoint. This is principally because decisional regret is predicated on the (improbable) understanding of outcome under the counterfactual. New paper shows regret is basically explained by "I had a bad outcome". pubmed.ncbi.nlm.nih.gov/42429300/

Hasn’t it been amazing to see teams from the minor footballing countries doing so well at the world cup, even if they come up short? I refer to Morocco, Egypt, Cape Verde and, of course, England.

When I report that I am doing a randomized trial, this is in distinction to a study with non-randomized or historical controls. But when a researcher claims to be analyzing "real world data", this is in distinction to what exactly?

Looking for the best papers on the positive and negative likelihood ratio for prostate MRI. What is LR+ and LR- separately for PIRADS 3, 4 and 5? Problem is, this can only be derived from a study where everyone had a biopsy or long-term follow-up.

Has anyone been noticing folks are starting to say "numerically superior" to describe results that are not statistically significant?

Can someone explain to be how, in meta-analysis, leave-one-out methodology, has anything to do with exploring the sources of heterogeneity?

PSA screening reduces cancer-specific mortality (PCSM). Questions remain about effect on all-cause (OS). PSA could reduce PCSM not OS only with deaths from other causes, eg complications of surgery. Please reply with list of screening-induced causes of death.

Analysis of the CAP randomized trials demonstrates prostate cancer overdiagnosis is highly age dependent. Opportunistic screening policies have led to most PSA tests being in older men. These policies should be revaluated. onlinelibrary.wiley.com/doi/10.1002/ijc.70492

97% of the papers archived the data but only 35% archived the code. Most people are writing code but not sharing it. Time to bring up this again: scispace.com/pdf/publish-... (and if the code isn't good enough yet, maybe it's too early to publish the paper) #openscience #reproducibility #ecopubs

If only AI / ML had been around when I was training, I wouldn’t have had to learn about things like causal inference, how to evaluate prediction models or even, say, the importance of data quality. What a waste of time all that was!

Any suggestions as to great resources (lectures on YouTube, short didactic papers etc), to teach novice researchers about RCTs? Design, endpoints, consent, eligibility criteria, IRB etc etc any and all of it.

Too many meta-analyses have findings equivalent to: “If you average the cost of a loaf of bread, car insurance for a year and a movie ticket, you get $752.36”

1) A covariate that is predictive of outcome should be in the model even if unpredictive of assignment (eg matched pairs design). 2) A covariate that is not predictive of outcome should not be in the model, even if predictive of assignment. 3) The propensity score is stupid.
