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

Undernutrition and low dietary quality remain widespread issues in Africa. As most rural households in the region are involved in farming, the diversification of own farm production could improve their access to nutritious foods. Here we use representative panel data from six African countries to estimate this effect across different scales. We show that farm production diversity is positively associated with household dietary diversity-yet the average magnitude of the association is small, depends on the specific measure of production diversity and increases with distance from urban centres. In all countries, markets and market access are more important for dietary diversity than own production. Because village-, town- and district-level production diversity are often positively associated with dietary diversity, higher diversity on each individual farm may not be required. The appropriate spatial scale should be considered when designing diversification strategies.
