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

Giardia intestinalis is comprised of two major genotypes, A and B, which may vary in their propensity to cause disease. We tested for the presence of these two genotypes in stool samples from patients with gastrointestinal symptoms in Nepal. A total of 1,096 clinical specimens were screened by microscopy, and 45 samples with G. intestinalis were identified. Giardia infection was confirmed in 35 of 45 samples by a Giardia specific real-time polymerase chain reaction (PCR) assay. Genotyping of the Giardia PCR product by restriction fragment length polymorphism indicated that 74% (26 of 35) were assemblage B, 20% (7 of 35) were assemblage A, and 6% (2 of 35) were mixed assemblages.
