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

Homestead food production (HFP) can improve nutrition through multiple pathways. Understanding their relative importance can optimize intervention design and impact. Here we used panel data on 2,612 women from a 1:1 cluster-randomized trial of 96 settlements in rural Bangladesh and conducted multiple mediation analysis to investigate the impact pathways of a 3-year HFP intervention on women's dietary diversity. The pathways analysed fully explained the intervention's total effect on dietary diversity score, amounting to an increase of 0.4 (95% confidence interval (CI) 0.3-0.5) food groups on a 10-point scale. Garden production accounted for 78% of the increase (β = 0.33 (95% CI 0.25-0.42)), emerging as the key component to improving dietary diversity. Nutrition knowledge accounted for 18% of the increase, while poultry production and market activity made smaller contributions. These findings can guide the design of future HFP interventions, but similar analyses are needed across a range of interventions, outcomes and settings to build a robust evidence base for improving nutrition.
