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

backgroundTo investigate the association between low transthyretin (prealbumin) concentration and mortality or readmission for all causes in elderly inpatients.

methodsThis analysis is based on a prospective cohort study conducted from September 2018 to April 2019 in ten wards of three tertiary referral hospitals in Beijing. Patients aged 65 years or older were enrolled, and their clinical data, laboratory test results, and auxiliary test results for patients were collected. A three-year follow-up was conducted with patients. Based on the 5th and 95th percentiles of transthyretin concentration, patients were split into three groups. The correlation between transthyretin concentration and the outcome of elderly hospitalized patients was investigated. The primary outcome of the research was death or readmission from all causes within three years.

resultsAmong the 636 individuals in the study, 335 (52.7%) were males, with a median age of 74.7 years (interquartile range [IQR]: 69.3-80.1). During a median follow-up period of 1,099.0 days (IQR: 1,016.3-1,135.0), 363 individuals (57.0%) experienced all-cause mortality or readmission events. Patients with transthyretin concentrations at or below the 5th percentile had a significantly increased risk of all-cause mortality or readmission compared to those with concentrations between the 5th and 95th percentiles (hazard ratio [HR]: 2.25; 95% confidence interval [CI]: 1.55-3.26). Even after adjusting for potential confounders, low transthyretin concentration remained an independent risk factor for poor prognosis in elderly inpatients (HR: 1.84; 95% CI: 1.03-3.28). Since women have consistently lower baseline transthyretin levels than men, we performed gender-specific analysis. We found that low transthyretin concentration is an independent risk factor for adverse prognosis in elderly male inpatients (HR: 2.99; 95% CI: 1.35-6.62) but not in females.

conclusionsLow transthyretin concentrations are associated with increased all-cause mortality or readmission in elderly inpatients, particularly among male patients.
