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 effects of supplementing Bovans Brown chickens with green vegetable leaves (beetroot, spinach, and cabbage) on egg yield, quality, and economic performance. The experiment was carried out using a complete randomized design (CRD) with four treatments: T1 (commercial ration), T2 (commercial ration + 300 gm head cabbage leaf), T3 (commercial ration + 300 gm spinach leaf) and T4 (commercial ration + 300 gm beetroot leaf) with four replications. One hundred forty-four (144) chickens, weighing around 1375.4 g (24 weeks old), were chosen at random and placed in sixteen (16) pens, each with nine (9) chickens housed in a deep litter house. Results revealed that leaves of beetroot, spinach, and cabbage had 90.9, 94.3, and 92.6 DM (%) and 12.9, 11.2, and 14.7 CP (%), respectively. T4 had a greater percentage of hen-day egg production (74.1 %). The egg mass of T3 (65.6 ± 0.5 g) was higher than T1, T2, and T4 treatments. The albumen weight in T3 (42.6 ± 0.6 g) was significantly higher (p < 0.05) than T1, whereas egg weight, shell thickness, Haugh Unit, albumen diameter, yolk diameter, and yolk weight were not significantly affected. T4 had greater returns from the selling of eggs and chickens than other treatments. It was determined that beetroot leaves seemed to be an advantageous supplement to layers' diets and that they were reasonably priced.
