What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Google Scholar, Medline/PubMed, Cochrane Library, Science Direct, CINAHL Complete and OVID databases were used for study search. Inclusion criteria was based on PICOS. The quality of the studies was assessed using the Joanna Briggs Institute-Meta analysis Statistical Assessment and Review Instrument (JBI-MAStARI). 10 studies were included in the systematic review after those excluded due to reasons not meeting the inclusion criteria.
resultsIt was determined that the sample size was 50 or more in 80% of the studies. It was determined that the maximum number of laughter yoga sessions was 24 and at least 5 sessions. It has been observed that stress levels evaluated with different measurement tools decrease with the effect of laughter yoga in four studies. In three studies it was found that the level of burnout decreased after laughter yoga.
