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

This study was conducted to evaluate the impacts of a probiotic-enzyme complex (PEC) on laying performance, egg quality, intestinal health, and serum metabolite levels in laying hens fed a low-protein diet. A total of 720 Hy-Line Brown laying hens aged 45 weeks were randomly allocated into three groups, with six replicates per group and 40 hens per replicate. The experiment lasted for 10 weeks. The high-protein (HP, 17% CP) group was fed a high-protein diet, whereas the low-protein (LP, 15% CP) group received a low-protein diet, and the PEC group was fed the same LP diet supplemented with the 0.1% PEC (consisting of
