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

aimsTo investigate whether oral glucose tolerance test (OGTT) 1-hour plasma glucose (1-h PG) concentration can be used as the criterion for diagnosing diabetes mellitus (DM) and pre-diabetes. MATERIALS AND

methodsData were collected from 1021 outpatients who completed a 5-point OGTT. The χ

resultsThe prevalence rates of diabetes and pre-diabetes were 34.1% and 24.4% based on the American Diabetes Association (ADA) standard, 42.4% and 21.8% when OGTT 2-h PG was replaced with OGTT 1-h PG, and 44.4% and 20.8% when the OGTT 1-h PG was added to the ADA criteria. According to the WHO criteria, the prevalence rates of diabetes and pre-diabetes were 30.4% and 19.2%, 40.5% and 21.8% when OGTT 2-h PG was replaced with OGTT 1-h PG, and 43.9% and 22.2% when the OGTT 1-h PG was added to the WHO criteria. Substituting OGTT 1-h PG for OGTT 2-h PG in the ADA diagnostic strategy still retained good consistency for both diabetes (κ=0.7, 95% CI 70.1% to 78.4%) and pre-diabetes (κ=0.7, 95% CI 64.5% to 75.0%). For diabetes, the area under the curves (AUC) was 93.7% (95% CI 92.2% to 95.1%) for OGTT 1-h PG and 96.1% (95% CI 94.7% to 97.3%) for OGTT 2-h PG. For pre-diabetes, the AUC was 71.8% (95% CI 67.9% to 75.8%) for OGTT 1-h PG and 70.4% (95% CI 65.9% to 74.5%) for OGTT 2-h PG.

conclusionsThe DM prevalence would be significantly higher if the OGTT 1-h PG was adopted as the diagnostic criterion. More prospective studies are needed to validate its clinical utility.
