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

background/obejctiveAlthough the high-protein diets (HPDs) on weight control and body composition management are well investigated, mix results have been reported across studies and this variability may be attributed to differences in the composition of other macronutrients within HPDs. The aim of this study was to evaluate the impacts of HPDs with varied macronutrient compositions on body composition and cardiometabolic health outcomes through a systematic review, pairwise, and network meta-analysis.

methodsA comprehensive search of four databases (PubMed, Embase, CINAHL, and Web of Science) was conducted to identify relevant randomized controlled trials. A total of 83 articles were selected for systematic review and both meta-analyses.

resultsSignificant reduction in body mass (BM) (standardized mean difference [SMD] = -0.25; 95% CI: -0.40, -0.11), body mass index (BMI) (SMD = -0.26; 95% CI: -0.38, -0.15), waist circumference (WC) (SMD = -0.19; 95% CI: -0.33, -0.04), fat mass (FM) (mean difference [MD] = -0.64 kg; 95% CI: -0.98, -0.29), along with increase in lean body mass (LBM) (MD = 0.34 kg; 95% CI: 0.11, 0.57) were observed with HPDs regiments compared to normal-protein diets. Specifically, the high-protein, moderate-carbohydrate and high-fat diet ranked the best in reducing BM, BMI, WC, FM, systolic blood pressure, diastolic blood pressure and increasing LBM; while the high-protein, low-carbohydrate and high-fat diet obtained the highest score in reducing triglyceride and increasing high-density lipoprotein cholesterol.

conclusionHPDs effectively reduce FM and increase LBM, and offers potential cardiometabolic benefits. Additionally, the manipulation of carbohydrate content in HPDs may further influence these outcomes. REGISTRATION: PROSPERO (CRD42023483907).
