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

Phase angle measured by bioimpedance is considered to reflect muscle quality and nutritional status. This study investigated the associations of phase angle and its 5-year change with all-cause mortality among community-dwelling older Japanese adults. A total of 1,291 Japanese adults aged ≥65 years with phase angle measured in 2012 were followed-up for a median of 10.3 years. Participants were divided into age-and sex-specific quartiles of phase angle and into quartiles of 5-year change in phase angle beyond standard age-related decline, defined as the difference between actually measured and estimated values from the linear regression line between phase angle values measured in 2007 and 2012. Hazard ratios (HRs) for all-cause mortality were estimated using Cox proportional hazards models. During follow-up, 347 participants died. The lowest quartile of phase angle showed a higher risk of all-cause mortality compared with the highest quartile after multivariable adjustment (HR 1.49, 95% CI 1.10–2.02). A similar trend was observed for 5-year change in phase angle beyond age-related decline (HR 1.42, 95% CI 1.03–1.97). Lower phase angle and greater decline beyond age-related expectations were associated with increased mortality risk. Phase angle may provide a simple, noninvasive measure of mortality risk in older adults.
