Okay…but that has nothing to do with p-values. Cliff, the thing is that p values by themselves are unassailable mathematical facts: “If you generated random numbers using my chosen RNG program “NullHypothesis(i)” you would rarely see a dataset stranger than the data D[i] as measured by test statistic t(Data), (p = 0.0122)”. Just a small gloss on that — A former colleague argued that the reason 0.05 is used as a filter is that a result that can’t be p-hacked to get below 0.05 shows that the effect can’t possibly be there! With p=.06, I’m just very slightly more skeptical. so I am thinking more thought about bias correction would be better (despite how tricky that might be https://www.ncbi.nlm.nih.gov/pubmed/12933636 ).

Therefore *even if* we were willing to use a p-value threshold in principle, we shouldn’t get excited by a difference of p=0.04 vs p=0.06 because the estimate of p is just too noisy.

And clinical research is all about using the right words and the footnotes, as Ewan points out. The mean (SD) age of the patients was 69.6 (16.0) years for the safety-net hospitals and 74.9 (14.7) years for the non–safety-net hospitals; 9382 (48.8%) and 7003 (48.5%) patients, respectively, were female. I assure you that all studies “looking for an effect” like this will be totally ignored in a few hundred years, they have no role in accumulation of knowledge.

For instance, I believe I was unable to convince David F Andrews (U of T) that meta-analysis was a good idea because I think he thought if you only analysed one study on its own, you avoided publication bias, whereas if you dealt with all published studies together you could not avoid it (or fix it). { bidder: 'ix', params: { siteId: '555365', size: [160, 600] }}, { bidder: 'ix', params: { siteId: '555365', size: [300, 250] }}, name: "idl_env", How do we create a person’s profile?
