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
objectivesSocial isolation is a concern among aging populations, and household composition may play an important role in its impact on mental health. We use data from an aging cohort in rural South Africa to investigate the moderating role of household size and both gender and age composition in how declining extra-household social contact during the COVID-19 pandemic impacted anxiety.
methodsThe participants included in the data completed both wave 3 of Health and Aging in Africa: A Longitudinal Study of an INDEPTH Community (HAALSI) and a temporally overlapping COVID-19 phone survey (July 2021-March 2022) (n = 2,054). We measured anxiety using a modified 2-item Generalized Anxiety Disorder scale and used household size and the numbers of women, men, older adults (ages 60+), and children (<age 15) in the household as modifying measures. Analyses used gender-stratified generalized estimating equations with a logit link.
resultsAmong both women and men, a decrease in in-person social interaction was associated with greater odds of increased anxiety during the same time period. Living in larger households, households with more men, and households with more children increased the magnitude of the association between decline in in-person interactions and odds of increased anxiety for women. We did not find significant modifying effects for men. DISCUSSION: We speculate that these results stem largely from the caregiving burden, which falls more heavily on women than men, especially among the aging population in this setting. Furthermore, they have implications for aging adults who may experience greater social isolation with age.
