I’m thrilled that leading research groups now recommend our #ICEMANtool to evaluate possible subgroup effects:
#Cochrane in their handbook Chapter 10.6
#GRADE in their guidance No. 36
Germany's #IQWIG in their general methods

Ian Fleming's original James Bond novels haven't aged well. For example, Moonraker - published almost exactly 70 years ago in April 1955 - features a villain who's a super-rich industrialist and rocket-maker seeking to cause chaos because he's a secret Nazi. Such a silly idea!

A better statistic might be the prediction interval but in my view the community needs to develop more experience with it before we can use it to confidentially judge relevance of heterogeneity (if ever). And unfortunately it does not work very well in a meta-analysis with only a few studies

Stefan Schandelmaier @sschandelmaier.bsky.social · Jan 3

True. But what else can we do? A paper in the new Core GRADE series (currently under revision in the BMJ) offers a practical solution based on visual inspection of both overlap of confidence intervals (similar to I2) but also where point estimates lie in relation to a relevance threshold.

Vaccines stopped polio.

The image is a graph titled "Reported paralytic polio cases and deaths, United States, 1910 to 2019," from Our World in Data. It shows the annual number of polio cases (in red) and deaths (in green). A sharp decline in both cases and deaths occurs after the introduction of the polio vaccine in 1957, which is marked with an arrow labeled "Vaccine introduced in 1957." The graph illustrates the dramatic impact of vaccination on reducing polio cases and fatalities over time.

1/ Excited to share thoughts on two excellent blog posts about clinical trials! First up: "The Case for Clinical Trial Abundance" by @ruxandrabio.bsky.social and Willy Chertman . They argue we need more clinical trials & that bureaucracy hampers faster progress. A sentiment I fully share!

Methods guidance is evolving. Here the authors chose to provide explicit recommendations both in favor but also agains certain methods. I think that that’s the way forward!

Does #randomization ensures balance of risk factors between groups? Consider this:

In Denmark 860 individuals were randomly allocated to either intervention or control. Individuals were unaware of their allocation. No intervention took place. Mortality was higher in the intervention group (p=0.003)

Hi qualitative researchers!

For my teaching, I was searching for something like PICO for qualitative. I found SPIDER and like it! pubmed.ncbi.nlm.nih.gov/22829486/

Is anybody aware of any other scheme for systematic question / problem / objective formulation in a qualitative study?

For patient-focused research, there are very few useful research aims, and none of them are "identifying risk factors.”
