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

Legumes are a rich source of dietary fibre, plant protein, and low-Glycaemic Index (GI) carbohydrate. Evidence suggests a positive effect on glycaemic control following a single meal; however, the effects of habitual consumption are less clear. This review aimed to investigate whether medium-to-long-term legume consumption had an effect on markers of glycaemic control in individuals with diabetes mellitus, without diabetes mellitus, or with prediabetes. As per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol, the online databases MEDLINE, Embase, CENTRAL, and CINAHL were searched from inception through to 31 March 2020. Randomised controlled trials (RCTs) ≥6 weeks in duration, reporting ≥1 of the following: fasting blood glucose (FBG), fasting blood insulin (FBI), glycosylated haemoglobin (HbA1c), homeostatic model assessment-insulin resistance (HOMA-IR), or 2-h postprandial glucose (2-h PPG), were deemed eligible. The overall quality of evidence was determined using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) assessment. A total of 18 RCTs were included, of which, 5 focused on individuals with diabetes mellitus, 12 on individuals without diabetes mellitus, and one on individuals with prediabetes. Only studies of those with type 2 diabetes mellitus (
