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

Fecal pH is used in canine nutrition studies as an indirect indicator of intestinal fermentation, but sample preparation may affect the measured value. This study evaluated the effect of different feces-to-water dilution ratios on pH determination in canine feces. Thirty-seven samples from 20 healthy dogs were evaluated using five preparation protocols: direct measurement without dilution and dilution with distilled water at 1:1, 1:2, 1:5, and 1:10 feces-to-water ratios, on a weight-to-volume basis. Sample preparation affected fecal pH (
