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

Starch overload induces dysbiosis primarily through a reduction in cecal pH. This study aimed to evaluate the cecal microbiota following excessive starch intake, with or without the administration of an intracecal buffering solution. We hypothesized that the buffering solution would mitigate changes in the intestinal microbiota and associated clinical signs. Ten horses were randomly assigned to two groups, each receiving distinct treatments (Group I: saline solution [WSa] and starch-buffer [SB]; Group II: buffer-water [WB] and starch-saline [SSa]). Following starch overload (17.6 g/kg body weight via nasogastric tube), clinical assessments and cecal content sampling were conducted at six time points (T0, T08, T12, T24, T48, T72), corresponding to 0, 8-, 12-, 24-, 48-, and 72-hours period. DNA was extracted, and the V4 region of the 16S rRNA gene was amplified and sequenced using the Illumina platform. Sequence data were processed using QIIME2. Statistical analysis was performed using the ExpDes package in R, with means compared via Tukey's test. Diversity analysis revealed decreased richness and evenness post-treatment in Group I, with reductions observed as early as T08 in the SB treatment. The relative abundance of
