1 · What the graph read from 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.

2 · The registry

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

backgroundThe present work focused on investigating the frailty status of older nursing home residents by analyzing the relationships among loneliness, sarcopenia, and frailty. The study explored the mediating effect of sarcopenia on loneliness and frailty among elderly individuals.

methodsFrom January to June 2022, 190 elderly individuals were enrolled from four nursing homes in Guangzhou, Dongguan, Zhanjiang, and Nanning using a convenience sampling method. A field survey was conducted using a sociodemographic questionnaire, the Frailty Phenotype, the UCLA Loneliness Scale, and the SARC-F screening tool. The data were analyzed with SPSS 25.0 and Process 4.1 software. Normally distributed continuous variables are presented as the means ± standard deviations (Mean±SD) . Associations among loneliness, sarcopenia, and frailty were assessed via Pearson correlation analysis. Moreover, the mediating effect of sarcopenia on loneliness and frailty was examined via linear regression. The bootstrap method in Process 4.1 was employed to test its mediating effect.

resultsThe frailty prevalence among elderly nursing home residents was 34.74%. The loneliness score was positively related to the frailty score (r = 0.156, P < 0.05, 95% CI:0.014-0.292), the sarcopenia score was positively related to the frailty score (r = 0.512, P < 0.01, 95% CI:0.399-0.610), and the loneliness score was positively related to the sarcopenia score (r = 0.214, P < 0.01, 95%CI:0.074-0.346). Sarcopenia demonstrated a complete mediating effect on loneliness and frailty among elderly nursing home residents. Sarcopenia typically achieved a mediating effect of 0.107 (95% CI: 0.026-0.197), accounting for 68.59% of the overall effect.

conclusionsSarcopenia is a key factor influencing the occurrence of frailty in lonely elderly individuals in nursing homes.
