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.

Abstract

contextThe impact of dietary protein on body composition changes after older adults purposefully lose weight requires systematic evaluation

objective: This systematic review and meta-analysis assessed the effects of protein intake (< 25% vs ≥ 25% of energy intake or 1.0 g/kg/d) on energy restriction-induced changes in body mass, lean mass, and fat mass in adults older than 50 years. DATA SOURCES: PubMed, Cochrane, Scopus, and Google Scholar were searched using the keywords "dietary proteins," "body composition," "skeletal muscle," and "muscle strength." STUDY SELECTION: Two researchers independently screened 1542 abstracts. DATA EXTRACTION: Information was extracted from 24 articles. DATA SYNTHESIS: Twenty randomized control trials met the inclusion criteria.

conclusionOlder adults retained more lean mass and lost more fat mass during weight loss when consuming higher protein diets.
