How is the Beginning and End of Frequent Laughter Associated With Changes in Loneliness Amongst Older People in Japan? A JAGES Longitudinal Study.

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
objectiveLittle is known about the association between frequency of laughter and loneliness-in particular based on longitudinal data. Therefore, our aim was to examine how the onset and the end of frequent laughter is associated with changes in loneliness amongst older people in Japan. METHODS/
designLongitudinal data were taken from the Japan Gerontological Evaluation Study (JAGES, waves 6 and 7 with n = 5262 observations, mean age was 74.4 years, SD: 5.8 years). The widely used and psychometrically sound UCLA-3 was used to quantify loneliness. Frequency of laughing served as key independent variable. Asymmetric linear fixed effects regressions were used, adjusting for several time-varying covariates.
resultsAfter adjusting for several sociodemographic, lifestyle-related and health-related time-varying factors, there was a significant association between the onset of frequent laughing and decreases in loneliness (β = -0.18, p < 0.05). Age and sex did not moderate this association. In contrast, the cessation of frequent laughter was not significantly associated with changes in loneliness.
conclusionsStarting frequent laughter may help to avoid negative consequences such as loneliness among older adults in Japan. This may emphasize the importance of finding ways to start laughing frequently. Efforts to reduce loneliness are important because it is in turn associated with outcomes such as morbidity and mortality.
