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

Efficacy of a dual-strain Bacillus subtilis complex (597 and 600) on productive performance, egg quality, apparent ileal digestibility (AID), serum parameters, selected cecal bacterial populations, tibia traits, and economic efficiency in laying hens was investigated. A total of 324 Hy-Line Brown hens at 18 wk of age were randomly assigned to two dietary treatments with 18 replicates of 9 birds per cage for a 22-wk trial divided into Phase 1 (wk 18 to 29) and Phase 2 (wk 30 to 40). Diets included a control diet (CON) and CON supplemented with 0.01% probiotic complex (PRO; 1.3 × 10
