#evidencesynthesis — Public Fediverse posts

Here's a fun one for #EvidenceSynthesis / #SystematicReview crowd 📚

@ZijunLi and me are doing a meta-analysis where we compare two groups.

We use the "Cohen's d" family of effect size metrics for the meta-analysis (comparing baseline to follow-up, immediate and later)

Some studies (e.g. smoking interventions) only report a percentage in each arm (e.g. % of smokers).

How to best convert these percentages into smth Cohen's d-ish? 🤔

We appreciate any help / boosting!

Does anyone have experience with CADIMA for screening articles? www.cadima.info I’d be interested in hearing thoughts, especially if you can compare it to rayyan #evidencesynthesis #systematicreview

This was a huge work that we just got published on trends and patterns in evidence synthesis within the field of Forestry and Forest-based Sector (F&FS) . The study investigates potential biases in evidence synthesized by examining different forms of synthesis (i.e. systematic and non-systematic), topics covered and geographical distribution of underpinning studies.
Reviewed topics are dominated by #ForestManagement, #Biodiversity and #ClimateChange, even though the field is sprawling away from core silviculture themes and into more transdisciplinary issues.

Big news. I’ve started a new position as Principal Investigator at the University of Coimbra 🇵🇹

I'm joining the meta-research group led by @T_Weissgerber and the EXCELScIOR ERA Chair project (https://excelscior.uc.pt/) funded by the @EUCommission

I'm thrilled to join this historic university & continue my work on #MetaResearch #EvidenceSynthesis & #OpenScience

The new office, at the Palácio dos Grilos, could not be more iconic 👇

As interesting as the topic is, I'm really glad it's not up to me to fix this mess

#ESMARConf2025 is live now (https://www.youtube.com/@esmarconf), starting with a talk by @ASanchez_Tojar on "Practising what we preach: Rethinking standards in meta-analysis for ecology and evolution".

At 11am (CEST), I will give a talk on how to visualize the amount of heterogeneity in forest plots.

1/3 In a recent paper, we described the use of location-scale models in meta-analysis to not only examine how moderators may be related to the size of the effect, but also how moderators may be related to the amount of heterogeneity among the effects: https://doi.org/10.1002/jrsm.1562

Such models can be fit with the metafor package in R: https://wviechtb.github.io/metafor/reference/rma.uni.html#location-scale-models

Can anyone explain to me the relationship between the "SHOW ME the evidence" paper published in JBI Evidence Implementation, Campbell Systematic Reviews, Clinical and Public Health Guidelines, Cochrane, and Environmental Evidence in November, and the "Evidence Synthesis Infrastructure Collaborative"?

Wow, PROSPERO look very different and it sounds like it is very different.
This is a great idea IMO

And here it is: where you can request free access to Policy Commons to search for #GreyLit for an #EvidenceSynthesis project:

OK I know that #EvidenceSynthesis is becoming a bigger part of the literature but I didn't realize the rate was climbing this steeply, or that it's already so high.
More than one in twenty articles in PLOS ONE have been systematic/scoping/rapid reviews, or their protocols, for two years and a bit? Seems surprising.

Today is the day. We are hosting the workshop at Bielefeld University

"The #EvidenceSynthesis Toolkit: Perspectives from Philosophy and Biology"

Unmatchable list of speakers

The first gen AI study that I really want to read (maybe even do):
1 recruit participants WITH DIFFERENT LEVELS of experience in evidence synthesis and searching
2 show them chatbot output for prompts like "pretend you're a medical librarian and create a SR search strategy to use in PubMed for my research question," using whatever the state of the art guidelines are for "prompt engineering"
3A ask the participants to evaluate the chatbot output

For 1000 *protocols* of *living* systematic reviews, how many reviews get published, and how many continue to be updated on the original schedule? Anyone have an estimate?
#medlibs #EvidenceSynthesis

Have you ever seen an SR that did a sensitivity analysis based on only the OA included papers? Or even pointed out how many of the included papers are OA? Would love to read examples, don't care if they included only version of record OA or not.

Last week, I gave a talk about model selection in complex meta-analyses. It covers some general model considerations and gives several examples of multilevel and multivariate meta-analyses. You can find the slides for this presentation (and the code for the examples) here: https://www.wvbauer.com/doku.php/presentations

Anyone attending #GES2024, as well as anyone interested in #EvidenceSynthesis who will be in Prague on September 9, might want to attend the free "Introduction to EPPI-Reviewer" workshop.
