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 registryThe 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.

6 · The paper itselfAbstract
Despite a decade of indoor residual spraying, malaria remains holoendemic in Nchelenge District in northern Zambia. This study examined the hypothesis that the intransigence of malaria in Nchelenge District is due in part to early evening and outdoor foraging of local anopheline species. Three replicate collections were performed at 24 households using CDC light traps over 6 weeks during the dry season of 2019. Traps were set indoors, in animal pens, and in outdoor gathering spaces from 16:00-22:00, and overnight indoors in all households during the third replicate. Twelve anopheline species were collected in early-evening traps. The major vector,
