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

backgroundThe virulence of Plasmodium falciparum is associated with the capacity of the infected red blood cell (iRBC) to adhere to uninfected RBCs, a process known as rosetting, which has been linked to the occurrence of severe malaria. The present study was carried out in three Ethiopian malaria endemic localities to investigate the relationship between blood group type and severe disease in falciparum malaria.

methodsA total of 210 cases of malaria (70 severe and 140 uncomplicated) and 190 healthy controls participated in the study. Patients with at least one of the severe malaria syndromes (cerebral malaria, severe anaemia and circulatory collapse) were considered as severe malaria cases.

resultsIn the severe malaria category, there were 25 (35.7%), 15 (21.4%), 14 (20%) and 16 (22.9%) blood group A, B, AB and O patients, respectively. Blood group O was the dominant blood type in both uncomplicated malaria (45.7%) and healthy controls (41.6%). A case of severe malaria was almost twice as likely to be of type A as to be of type O (odds ratio (OR) 0.42, 95% confidence interval (CI) 0.20-0.88, P = 0.019), and more than twice as likely to be of type B as to be of type O (OR 0.38, 95% CI 0.16-0.89, P = 0.02). Furthermore, individuals with severe malaria were about six fold less likely to be of O as to be of type AB (OR 0.19, 95% CI 0.07-0.51, P = 0.0005).

conclusionThe study revealed that on the basis of the three criteria (cerebral malaria, severe anaemia and circulatory collapse) used to determine severity in P. falciparum malaria, patients with blood group O, which is less prone to rosetting have a reduced chance of developing severe falciparum malaria as compared to patients with other blood groups.
