Effectiveness of Integrative Laughter Therapy to Reduce Anxiety, Improve Self-Esteem and Increase Happiness: A Naturalistic Study at a Day Hospital for Addictive Disorders.
Trial report in International journal of environmental research and public health, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
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
Little is known about the effectiveness of laughter therapy as an adjunctive treatment for patients with addictive disorders. This study aims to evaluate the benefits of integrative laughter therapy (ILT) on levels of self-esteem, anxiety, and happiness in patients treated for addiction at a day hospital (DH). A prospective, naturalistic study with a pre-post design was conducted. All 185 participants received the standard, multicomponent treatment at the DH (treatment as usual; TAU). The participants were also invited to attend weekly ILT sessions. Upon completion of the 2-month DH treatment program, patients were classified according to their attendance at the ILT sessions: patients who attended ≥80% constituted the experimental group (TAU + ILT group) while those who attended <80% were considered controls. Although both groups achieved statistically significant increases in self-esteem and happiness with a decrease in trait anxiety, the improvement on these variables was significantly greater in the TAU + ILT group. Subject to the limitations inherent to quasi-experimental research, the findings of the present study suggest that the addition of an ILT module to the standard treatment in a DH for addictive disorders may yield greater improvement in self-esteem, anxiety, and happiness compared to TAU.
