What Exactly Is Zheln?

In practice, Zheln has got two components: Zheln Records and Zheln Appraisals aka Health Science News.

Zheln Records

• Zheln Records are records that came from my Replicated Systematic Subset PubMed query retrieving most of all systematic reviews being published. They are different from plain PubMed records in that I’m tagging them with AMA specialty tags taken from the AMA Physician Masterfile specialty list, so you can browse Zheln Records by AMA Specialty, whereas on PubMed, locating all records relevant to your specialty requires use of very extensive search strategies and is, in practice, unfeasible. Of course, Zheln Record Search is also available.
• They are added daily (unless PubMed fails, and it does), most of them were published this fall, and each of them is counting as a true positive by Shojania & Bero 2001 criteria for systematic reviews. There are 864 recent systematic review records on Zheln currently.
• As you can see from the Zheln appraisal log and from the flow diagram below, only a (random) fraction of Replicated Systematic Subset records is processed as Zheln Records currently because this is a very high workload (roughly 500 new records daily on average), but not to worry: As soon as I crowd-raise enough money to keep Zheln running ($600/mo), I will make artificial intelligence do the stuff (in fact, it could manage even better than I do). This will involve discussions with machine learning specialists in evidence synthesis, such as Iain Marshall, and will allow stable processing of 100% of records.

Health Science News

• When I skim through the Zheln Records, I select the most appealing systematic reviews, critically appraise and replicate them, and record two-minute summary videos targeted at general audiences.
• As a rule, I select a review for a critical appraisal with replication when the topic covered is likely to have a very large practice impact with regard either to both global health care workers and the public or to the minorities. COVID-19 publications are not selected.
• Crowdfunding an appraisal is also possible.
• Some of the appraisals are already available as Health Science News on YouTube. Also, I make some of these natively available in Russian. Finally, all of these are also available from the Zheln Instagram channel.

Scientific Nuts & Bolts

• Zheln is not only an affiliation-free, nonprofit, health-educational project but also a formal scientific study.
• Read the preprint of the full-featured academic protocol for the Zheln overview of systematic reviews: DOI 10.31222/osf.io/y2nrb. I also submitted it for PROSPERO registration but was told processing the submission might take up to three months due to very high demand.
• It has not been peer-reviewed yet, but I’m eager! I welcome wide discussion and feedback of any sort very much, so please do engage me on Twitter or elsewhere!
• Also, I have started contacting the authors and publishers of the systematic reviews I appraise (first on Twitter, then, if no answer, by email) to collect more feedback and possibly resolve any content misunderstandings at my end. Please follow me on Twitter to engage in public discussions; I’m really looking forward to this!

Zheln Flow Diagram

This is the Zheln flow diagram. It shows the flow of systematic reviews on Zheln since the last summary post. The flow diagram is modified from the PRISMA 2020 Statement preprint by Matthew Page et al. and the SRflowdiagram tool by Neal Haddaway. I am deeply grateful to the original authors!
