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

We have previously mapped a locus controlling Plasmodium falciparum blood infection levels (PFBI) to chromosome 5q31-q33. We genotyped 19 microsatellite markers on chromosome 5q31-q33 in a new sample of 44 pedigrees comprising 84 nuclear families and 292 individuals living in a P. falciparum endemic area. Using a nonparametric multipoint variance-component approach (by GENEHUNTER), we evidenced a peak of linkage close to D5S636 (P=0.0069), with a heritability of 0.46. Using a variance-component method for linkage-disequilibrium mapping of quantitative traits (by QTDT) and the Bonferroni correction for multiple testing, we further detected allelic association in the presence of linkage between blood infection levels and D5S487 (P=6 x 10(-5); P(c)=0.0011), which is located on the distal part of the peak. These results confirm the importance of chromosome 5q31-q33 in the genetic control of PFBI levels.
