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

The aim of this research was to determine the effect of gut health parameters on the flock's final weight of broilers and to calculate an accurate equation to estimate this weight with information available at 7, 14, and 21 days, in field conditions. Gut health parameters (gizzard erosion, coccidiosis, feed passage, and redness, gut tone, consistency of content, and presence of mucus for each part of the small intestine [duodenum, jejunum, and ileum], and color, consistency, and presence of gas for caeca content) were evaluated at 7 and 14 days. Other parameters evaluated for impact on flock final weight were body weight and mortality, both at 7, 14, and 21 days; stocking density; litter reuse; and downtime period. Structural equation model evaluation of the data showed that stocking density and litter reuse did not affect (P > 0.05) flock final weight, while downtime period, body weight (14 and 21 days), and mortality (14 and 21 days) directly affected (P ≤ 0.05) the flock final weight. Gut health parameters did not directly affect the flock's final weight; however, they affected body weight and mortality at 14 days, thus showing an indirect effect on the flock's final weight. It was also possible to determine two accurate equations to estimate the flock's final weight using information available at both 14 (R
