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

Two hundred and three Plasmodium falciparum isolates from Jazan area, southwest Saudi Arabia, were typed for Pfcrt, Pfmdr1, dhps, and dhfr mutations associated with resistance to chloroquine, mefloquine, halofantrine, artemisinin, sulfadoxine-pyrimethamine, and the neutral polymorphic gene Pfg377. A large proportion (33%) of isolates harbored double mutant dhfr genotype (51I,59C,108N). However, only one isolate contained mutation dhps-437G. For Pfcrt, almost all examined isolates (163; 99%) harbored the mutant genotype (72C,73V,74I,75E,76T), whereas only 49 (31%) contained the mutant Pfmdr1 genotype (86Y,184F,1034S,1042N), 109 (66%) harbored the single mutant genotype (86N,184F,1034S,1042N), and no mutations were seen in codons 1034, 1042, and 1246. Nonetheless, three new single-nucleotide polymorphisms were detected at codons 182, 192, and 102. No differences were seen in distribution of drug resistance genes among Saudis and expatriates. There was a limited multiplicity (5%), mean number of clones (1.05), and two dominant multilocus genotypes among infected individuals in Jazan. A pattern consistent with limited cross-mating and recombination among local parasite was apparent.
