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

Climate change significantly impacts human health through extreme weather events such as heat waves and meteorological droughts, which increase vulnerability to various malaria diseases. This study examined drought-temperature influences on malaria incidence in Saki and Sepeteri, Oyo State, Southwest Nigeria, using monthly climate and health data from 2013 to 2023. Drought conditions were characterized using standardized precipitation indices (SPI-1, SPI-3, and SPI-12), and associations with malaria were analyzed using regression models accounting for seasonality and temporal lags. Malaria transmission was strongly seasonal, peaking during July-November, with mean monthly cases reaching 1,134 in Saki and 869 in Sepeteri. In Saki, long-term moisture availability significantly increased malaria incidence, with a one-unit increase in SPI-12 associated with a 267% rise in cases (
