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

An experiment was conducted to investigate the optimal dietary calcium (Ca) levels in Jing Tint 6 layer chicks fed different sources of zinc (Zn). A total of 1440 day-old birds with similar body weight (38 ± 0.5 g) were selected and divided into 10 groups with 6 replicates per group, each containing 24 chicks. The experimental period lasted from hatch to d 14. Diets were formulated to contain 2 sources of Zn: organic Zn (80 mg/kg Zn as hydroxy methionine Zn, HMZn) and inorganic Zn (80 mg/kg Zn as Zn sulfate). For each Zn source, 5 diets were formulated with Ca levels of 0.80%, 0.90%, 1.03%, 1.10%, and 1.20%, respectively. The results showed that dietary Ca significantly increased the average daily gain (ADG) (
