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

objectiveThis study aimed to examine the association between protein intake and risk of sarcopenia, with a specific focus on protein sources, in middle-aged and older adults.

designThis was a 9-year follow-up study. Dietary protein intake was assessed by a validated FFQ with energy adjustment using the residual method. Sarcopenia was defined by using height-adjusted appendicular lean mass and grip strength. Adjusted OR for sarcopenia were calculated by multivariable logistic regression analysis.

settingBaseline surveys (2011-2014) for the Murakami and Uonuma cohorts assessed body size, lifestyle and medical history. Sarcopenia-related measurements were conducted in 2021-2022 in Murakami, Sekikawa, Uonuma and Minamiuonuma, Japan.

participants6232 individuals aged 40-74 years (mean age, 62·4 years; females, 54·8 %).

resultsAn inverse association between plant protein intake and sarcopenia was observed in males (

conclusionsAn imbalanced intake of plant and animal proteins may increase the risk of sarcopenia, highlighting the importance of balanced protein intake.
