Why Zheln?
Hi, this is Pavel Zhelnov, the founder and the workforce of Zheln. I have launched this project in the hopes of bringing evidence closer to practice—the clinical practice, in the first place, but also to other activities associated with intervention into a human life, such as education, business, or policy.
Currently and for more than 10 years now, a wide gap has been recognized between the fast pace research is published and the limited capacity of evidence-based practitioners to promptly process it while also separating the practice-changing wheat from the chaff. And to my utmost disappointment, it is in contrast to a variety of solutions available that the call for a dramatic change is out in 2020.
Well, anyway, here I bring a change:
Every systematic review daily added to PubMed will get a rigorous, independent, and open-access critical appraisal.
This is the Zheln’s Mission.
How Is Zheln Different?
The idea of preappraised evidence summaries is all but new. Anyone in the field of evidence-based medicine is well aware of the ACP Journal Club, Cochrane Clinical Answers, or now legacy DARE summaries, just to mention a few. Not all of them cover secondary research only as Zheln does.
Anyway, I never found a resource that would have the following features at the same time (but if you did, I invite you to publicly discuss it on Twitter):
- Exhaustive research coverage
- Rigorous conduct appraisals with replication attempts
- Independence proven by full process transparency
- Full Open Access
- Easy to use
Then, in the Summer 2019, I felt like the launch of another was warranted; however, one more year was needed for me to get free of institutional agendas and set a course for this undertaking.
So What Does Zheln Offer?
Exhaustive Research Coverage
Nearly All Systematic Reviews Indexed by PubMed
Rigorous Conduct Appraisals with Replication Attempts
Zheln Review Appraisal in 10 Steps:
Step 1. Download All Records from a Daily Update for the Replicated Version of PubMed Systematic Subset
5,609 records uploaded to date (Sep 2 thru Sep 13, 2020).
Step 2. Record Appraisal: Does Meet Shojania & Bero 2001 True Positive Criteria for Systematic Reviews by Either Title or Abstract?
Just a couple of records have got past this stage by now because Zheln record screening methods are still in development. Namely, I’m developing a system to quickly process records in the Zheln format. Currently, development of the Zheln website was a priority, so the appraisals themselves got somewhat overdue.

Step 3. Collect Full Text or Other Review Reports for the Record
Step 4. Full Appraisal: Does Generate Pragmatic Evidence Directly Relevant to Evidence-Based Practice?
One appraisal has been started by now. I will complete it as soon as I have a good record triage system in place, because 5k+ records awaiting appraisal need to be processed ASAP.
Step 5. Full Appraisal: Is Duplicate?
Step 6. Full Appraisal: Did Pass or Fail Replication?
Step 7. Full Appraisal: Has Critical Conduct Flaws?
Step 8. Like or Dislike by Zheln
Step 9. Summarize Practical Implications
Step 10. Publish the Appraisal & Call for Crowdfunding
