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

objectivesLoneliness is increasingly recognized as a determinant of poor prognosis in older adults with chronic diseases, yet its impact on community-acquired pneumonia (CAP) remains unclear. This study investigates the association between loneliness and long-term adverse outcomes in older CAP patients.

methodsThis is a multi-center, prospective cohort study. Patients aged ≥ 65 years with CAP were included from April 2021 to January 2023. At admission, self-reported loneliness, geriatric assessments, CAP severity, and laboratory parameters were evaluated. Participants were followed for 180 days post-discharge. The primary outcome was 180-day all-cause mortality; the secondary outcome was readmission for respiratory infection. Multi-variable Cox regression models assessed associations between loneliness and outcomes.

resultsA total of 619 older patients were included in the analysis, with a median age of 78 years, and 12.8% reporting loneliness. During the 180-days follow-up, all-cause mortality and respiratory infection-related readmission rates were 8.7% and 10.5%, respectively. After adjusting for confounders, lonely patients had a nearly twofold higher risk of 180-days post-discharge mortality compared to non-lonely group (adjusted HR:2.047; 95% CI:1.036–4.044) and no significant association was observed with hospital readmission.

conclusionsLoneliness is an independent risk factor for all-cause mortality in the older patients with CAP. The assessment of loneliness and the implementation of targeted interventions may improve the long-term outcomes.
