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

backgroundLittle is known about life expectancy (LE) with or without frailty. We aimed to estimate the total LE and duration of the state of frailty in China.

methodsThis study included older adults aged 65 years and older from the Chinese Longitudinal Healthy Longevity Study (CLHLS). Frailty status was classified into robust, pre-frailty and frailty based on a cumulative deficit model. Total and specific frailty state LEs at 65 years of age were estimated and stratified by demographic characteristics, behaviours, and psychosocial factors using continuous-time multistate modelling.

resultsThe total LE of older adults aged 65 years in China was 14.74 years on average (95% CI: 14.52-14.94), of which 4.18 years (95% CI: 4.05-4.30) were robust, 7.46 years (95% CI: 7.31-7.61) pre-frail and 3.10 years (95% CI: 3.01-3.20) frail. Older adults with higher robust LE included men (4.71 years, 95% CI: 4.56-4.88), married older adults (4.41 years, 95% CI: 4.27-4.56), those engaging in physical activity (4.41 years, 95% CI: 4.23-4.59), those consuming fruits daily (4.48 years, 95% CI: 4.22-4.77) and those with high social participation (4.39 years, 95% CI: 4.26-4.53). Increased educational attainment were gradually associated with increased robust LE.

conclusionsFrailty may lead to a reduced total LE and robust LE of older adults in China. In addition to finding inequalities in total and robust LEs by socioeconomic status, our findings also highlight that healthy behaviours and social participation may ease frailty-related reductions in total and robust LE. Our findings imply that national life-course strategies aimed at frailty screening and psychosocial and behavioural interventions could be important for health aging in China.
