Zheln Is Your New Way to Experience Health News

Health News Are Often Misleading, but Not on Zheln

This is because only a single primary study is often presented, whereas on Zheln, you’ll find systematic reviews of studies only. Search for reviews now!

Also, the studies themselves may be misleading due to various problems arising from their conduct. Any comprehensive analysis of these problems or attempts to reproduce the review findings are rarely undertaken, while Zheln reviews are critically appraised thoroughly with focused replication (please check the academic Zheln protocol to see for yourself how good our methods are).

At the same time, spurious results are easily disseminated in health news. On Zheln, we cautiously propagate only the most credible, hard-won evidence. Watch Zheln Health News videos on YouTube or consult the list of reviews currently under appraisal.

Health news agencies are also rarely, if ever, independent entities. In contrast, Zheln is fully affiliation-free, fully open, nonprofit, and supported by crowdfunding only. Please help support Zheln.

This combination of systematicness, caution, and independence ultimately makes Zheln your best source of news about health.
