#EvidenceSynthesis

2026-01-13

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 (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

Hi #EvidenceSynthesis folks, is anyone using RAT for describing/choosing/improving information sources or search strategies for #SystematicReview project?

For anyone who’s published systematic reviews, how often did you succeed in getting unpublished data by reaching out to authors? I don’t mean additional/IP data from published papers, but new data or data they could not get published. #evidencesynthesis

Hi #EvidenceSynthesis folks
Am I the first person to read the TERA-Tools terms of use before signing up? The links in the TOU refer to an acceptable use policy and a privacy policy, but the hyperlinks don't work and I can't find them elsewhere on the website.
These TOU are dated 2023.... I get that "no one reads terms and conditions" -- but I am surprised that *literally* no one seems to have read it.

#ESMARConf2025 is live now (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.

Hi #EvidenceSynthesis folks and #medlibs
You have about ten minutes to give feedback to the ESIC people

Link: qualtricsxm45bq73zl3.qualtrics

The Stage 3 reports are at evidencesynthesis.atlassian.ne

Since you don't have time to read them at this point, I will suggest some talking points:

1 The AI working group's suggestion of generic classifiers (to tag/retrieve/screen studies with a particular study design, population, setting, outcome, whatever) is one of the few ideas that are IMO both valuable and feasible

2 You can say that technical mechanisms will someday allow for an AI-led framework where human oversight is significantly reduced, yet evidence integrity remains uncompromised – but saying that doesn’t make people believe it.

3 Before we build xkcd.com/927/ in terms of literature databases, or ES data sharing standards, or ontologies -- let's reflect on the benefits of decentralization. Would the rest of the EBM world be worrying quite so much about US politics if not for the centrality of NCBI, NLM, PubMed, PMC, CDC, HICPAC, NIOSH, etc in global information networks?

Someone explain to me -- I thought the whole point of considering using LLMs for #EvidenceSynthesis screening was to process large datasets quickly.
But in this paper
Ghossein, J., Hryciw, B. N., Ramsay, T., & Kyeremanteng, K. (2025). The AI Reviewer: Evaluating AI’s Role in Citation Screening for Streamlined Systematic Reviews. JMIR Formative Research, 9(1), e58366. doi.org/10.2196/58366
They had a human-labeled dataset of 1186 citations, and they only tested their LLMs on 121 of them -- all of the included studies and 9% of the excluded ones.

This, but replace "writing code" with "writing sensitive and reproducible #EvidenceSynthesis searches"
And replace "a requirements document" with "a systematic review protocol"

David Chisnall (*Now with 50% more sarcasm!*)
@david_chisnall@infosec.exchange

The reason I get so annoyed about people pitching LLMs as a way to 'democratise programming' or as end-user programming tools is that they solve the wrong problem.

The hard part of programming is not writing code.  It's unambiguously expressing your problem and desired solution.  Imagine if LLMs were perfect programmers.  All you have to do is write a requirements document and they turn it into a working program.  Amazing, right?  Well, not if you've ever seen what most people write in a requirements document or seen the output when a team of good programmers works from a requirements document.

What absolute perfect timing in light of the announcement that DOGE is cutting the size of ERIC significantly

Figure showing the overlap of Education Source, Education Database, Educator's Reference Complete, and ERIC. The first is much bigger and thus contains many more unique journals than the rest. The other three all contain more than 300 unique journals too.

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: doi.org/10.1002/jrsm.1562

Such models can be fit with the metafor package in R: wviechtb.github.io/metafor/ref

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
#EvidenceSynthesis #medlibs

During the registration process, the PROSPERO system uses the information provided to identify any similar reviews that have previously been registered. If similar reviews are found, and the person registering the current review decides to continue with their registration, they are asked to provide the reasons why their new review is needed (although this is not mandatory). The reasons provided (including none) become part of the registration record.
