Healing with laughter: the therapeutic power of laughter yoga in pediatric health - a systematic review.
Synthesis in BMC pediatrics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.

Abstract
backgroundLaughter yoga is a non-pharmacological and non-invasive therapeutic approach that integrates voluntary laughter with controlled breathing exercises. This systematic review aimed to evaluate research investigating the impact of laughter yoga on children's health outcomes.
methodsThis systematic review included studies with randomized controlled trial (RCT) and quasi-experimental designs, adhering to the PRISMA guidelines. This systematic review, conducted between December 18, 2023, and October 31, 2024, was guided by the PRISMA guidelines and a predefined protocol based on the PICOS-based protocol. Eligible studies included randomized controlled trials (RCTs) and quasi-experimental designs. A comprehensive literature search was conducted in Google Scholar, Medline/PubMed, Cochrane Library, Science Direct, CINAHL Complete, and OVID databases. Study selection was based on the PICOS framework, and methodological quality was assessed using the Joanna Briggs Institute-Meta Analysis Statistical Assessment and Review Instrument (JBI-MAStARI). Based on the inclusion criteria, six studies were incorporated into the review.
resultsThe total sample across the included studies was 305 participants, with 66% of the studies involving at least 50 participants. Findings indicated that laughter yoga contributed to a reduction in anxiety and stress levels in children (p < 0.05), while no statistically significant effect was observed on depression scores (p > 0.05). Although no substantial improvement in self-esteem was reported, positive changes in self-concept were noted. Furthermore, laughter yoga was associated with an increase in salivary IgA levels (p < 0.01), whereas no significant influence on cortisol levels was found (p > 0.05). Additionally, the intervention was reported to alleviate pain, fatigue, and burnout while enhancing hope and overall happiness.
conclusionsStudy results showed that laughter yoga promoted the increase in happiness and self-concept in children and improved their ability to cope with stress. It also provided a physiological improvement by positively affecting pain and fatigue. In light of these results, it is recommended that laughter yoga be used more widely in children's daily lives and clinical practices.
