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

Children with traditionally defined cerebral malaria (CM) can be subcategorized by the presence or absence of malaria retinopathy. We retrospectively reviewed the seasonal pattern of retinopathy status in patients admitted with CM in Blantyre, Malawi from 1997 to 2010. The proportion of children with CM who were retinopathy-positive was significantly greater during the peak seasonal rains when the community incidence of uncomplicated malaria is higher. This finding supports the hypothesis that retinopathy-negative and retinopathy-positive CM categories have different underlying etiologies.
