Meaning of upper limit of normal range of post-load 1-h plasma glucose level defined by oral glucose tolerance test in Japanese subjects.
Article in Journal of diabetes investigation, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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.
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
AIMS/
introductionTo identify upper limit post-load 1-h plasma glucose (1-h PG) after 75-g oral glucose test in a Japanese population. MATERIALS AND
methodsA total of 918 subjects were enrolled. We divided the subjects into two groups: normal 2-h post-load plasma glucose (2-h PG; <140 mg/dL) and impaired 2-h PG group (≥140 mg/dL).
resultsA total of 417 subjects had normal 2-h PG and 501 had impaired 2-h PG. The receiver operating characteristic (ROC) curve showed that the optimal cut-off value of 1-h PG was 179 mg/dL (area under ROC curve = 0.89), providing that the sensitivity, specificity, and positive and negative predictive value were 85, 79, 82 and 83%, respectively. The subjects with 1-h PG < 179 mg/dL consisted of 0.5% diabetes and 99.5% non-diabetes, whereas those with 1-h PG ≥ 179 mg/dL consisted of 26.9% diabetes and 73.1% non-diabetes (P < 0.01). Furthermore, there was a significant correlation between 1-h PG and 2-h PG (r (2) = 0.57, P < 0.01).
conclusionsThese data suggested that 179 mg/dL is the upper limit of the normal range of post-load of 1-h PG in a Japanese population. Thus, the subjects with 1-h PG ≥ 179 mg/dL might be at risk of developing future diabetes. Therefore, appropriate prospective study should be carried out to test this hypothesis.
