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

objectiveEpidemiologic evidence on the associations between dietary glycemic index (GI) and glycemic load (GL) and depressive symptoms is not only limited, particularly in Asian populations where dietary GI and GL are typically higher than in Western countries, but also inconclusive. This cross-sectional study examined these associations in Japanese women.

methodsSubjects were 3963 young (age 18-years) and 3826 middle-aged (mean age 47.8 years) Japanese women. Dietary GI and GL were assessed using a validated diet history questionnaire. Depression symptoms were defined as present when subjects had a Center for Epidemiologic Studies Depression score ≥16.

resultsThe prevalence of depressive symptoms was 50.2% for young women and 27.3% for middle-aged women. The mean (SD) values of energy-adjusted dietary GI and GL (GI for glucose = 100) were, respectively, 64.9 (4.3) and 142.0 (27.4) for young women and 65.0 (4.1) and 142.2 (29.5) for middle-aged women. After adjustment for potential confounding factors, higher dietary GI was associated with a lower prevalence of depressive symptoms. Adjusted OR (95% CI) for depressive symptoms in the highest compared to lowest quintiles of dietary GI was 0.66 (0.52, 0.82) for young women (P for trend = 0.001) and 0.75 (0.60, 0.96) for middle-aged women (P for trend = 0.046). Conversely, there was no association between dietary GL and depressive symptoms in either age group.

conclusionsDietary GI, but not GL, was inversely associated with depressive symptoms in a group of young and middle-aged Japanese women with relatively high dietary GI and GL.
