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

Enzymes have the potential to enhance nutrient utilisation and provide economic and environmental benefits in reduced protein (RP) diets; however, responses to different inclusion levels of phytase and carbohydrase enzymes remain inconsistent. Therefore, the present study aimed to evaluate the effects of phytase, xylanase, and β-glucanase inclusion levels in RP diets on nutrient digestibility and performance in laying hens. A total of 8 dietary treatments were allocated to 13 replicate cages of two hens per cage per treatment (n = 208) from 35 to 57 weeks of age. Experimental diets comprised two protein levels (standard protein (SP) at 16.5% crude protein versus RP at 14.5% crude protein), two phytase levels (600 and 1200 FTU/kg), and two XB levels (xylanase, β-glucanase 100 g/ton and 150 g/ton) were examined via a 2 × 2 × 2 factorial design. Between 35 and 57 weeks of age, no significant interactions were observed in laying performance parameters. However, RP diets significantly decreased egg weight across all periods, 35-47 weeks (
