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

Access to safely managed drinking water is a fundamental human right, essential for human health and well-being. However, 2.2 billion people around the world still lack this access, with significant geographical disparities. In this study, we leveraged the implementation of gender quota laws-specifically reserved parliamentary seats for women across African countries-to examine its impact on improved water availability. Our findings reveal that the implementation of gender quotas is associated with a 4.71 percentage point increase, on average, in the likelihood of people accessing safely managed water infrastructure. This effect becomes even more pronounced, rising to a 12.25 percentage point increase, when the quotas mandate reserving more than 20% of seats for women. Households with lower wealth, female-headed households, those living in rural areas, and households with lower levels of women's empowerment and education benefit most from this policy. Further investigation into the underlying mechanisms, and anecdotal evidence, reveals that gender-reserved seat quotas lead to an increase in the proportion of women in parliaments and an expansion of women's political and social rights, although these effects do not extend to economic status.
