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

Many environmental nonprofit groups are assumed to provide public goods. While an extensive literature examines why donors join and give to nonprofits, none directly tests whether donations actually provide public goods. We seek such a test by using a common form of environmental organization: watershed groups. We find their increased presence resulted in lower dissolved oxygen deficiency and higher proportions of swimmable and fishable water bodies. Increased donations to and expenditures by the groups also improved water quality. Thus, private groups likely played a role in mitigating environmental problems. Overall, our results indicate private provision of a public good by nonprofit organizations.
