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 evaluated the effects of dietary supplementation with soybean isoflavones (SIF) at 30, 50, and 100 mg/kg on reproductive performance, egg quality, ovarian function, tibia quality, serum hormone profile, antioxidant status, and immune function in late-phase laying hens. A total of 432 Hy-Line Brown hens with the average body weight of 2.18 ± 0.12 kg, aged 66 weeks, were randomly assigned to 4 dietary treatments: a basal diet (control) and basal diets supplemented with 30, 50, or 100 mg/kg SIF. The trial lasted for 8 weeks, with each group comprising 6 replicates of 18 birds. Results indicated that SIF supplementation at 30 and 50 mg/kg significantly improved egg production and albumen quality (
