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

Introduction: Due to the anti-inflammatory, antioxidant, and antibacterial properties of olive leaf powder (OLP), it may serve as a beneficial feed supplement for birds. This study aimed to evaluate the effect of adding OLP to feed on growth efficiency, carcass traits, blood parameters, antioxidant activity, and cecal microbial load in growing Japanese quail. Methods: Three hundred and seventy-five one-day-old quail chicks were randomly assigned to five experimental groups, each containing five replicates of 15 birds: a control group fed a basal feed and four experimental groups given 3, 4, 5, and 6% OLP per kg of quail diets for the 6 weeks. Results: The results showed a significant ( Discussion: The findings of this study demonstrate that OLP is a promising natural feed additive for growing Japanese quail, enhancing growth performance and the gut microbiome, thereby establishing it as a safe and natural growth promoter.
