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

Dietary fibre improves glycaemic control in type 2 diabetes, but its therapeutic role in women with diabetes in pregnancy is unclear. We assessed the effect of dietary fibre on markers of glycaemic control in women with diabetes in pregnancy.

methodsWe searched four databases (Cochrane Library, MEDLINE, Embase and Web of Science) to identify RCTs exploring the effect of dietary fibre, high-fibre diets or fibre supplementation on fasting blood glucose (FBG), 2-h postprandial blood glucose (PBG) and requirement for insulin therapy, among other glycaemic makers in pregnant women with diabetes. Data were pooled for each outcome to calculate change from baseline mean (SD) and overall mean difference (MD) between control and intervention groups.

resultsOf 1462 identified studies, data from 20 eligible trials containing 1061 participants were pooled. On meta-analysis, a higher fibre intake was associated with reduced FBG (MD: -0.35 mmol/L, 95% CI: -0.53, -0.18, p < 0.01), PBG (MD: -0.90 mmol/L, 95% CI: -1.39, -0.40, p < 0.01) and requirement for insulin (OR: 0.24, 95% CI: 0.13, 0.46, p < 0.01). There was significant heterogeneity for FBG and PBG (>90%), attributable to differences in Intervention type for PBG (Dietary Approach to Stop Hypertension [DASH] diet, low glycaemic index, supplement; p < 0.01) and study duration (for FBG: p = 0.002; not for PBG). Studies were mostly scored as high risk of bias due to lack of blinding (Cochrane Risk of Bias Tool v.2.0).

conclusionHigh-quality dietary intervention studies in pregnancy are lacking. Our results suggest that high-fibre diets improve fasting and postprandial glycaemia and reduce the likelihood of requiring insulin in women with diabetes in pregnancy.
