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

Background: Cinnamon oil, used as a feed additive in poultry, enhances growth performance, improves antioxidant status, and augments immune response, resulting in superior meat quality and general productive efficiency. Aim: This study aimed to assess the effect of cinnamon oil (CO) in broiler diets on growth efficiency, hematological parameters, gene expression, and histological condition. Methods: Two hundred sixteen one-day-old broilers were assigned to three treatments in a fully randomized design, with each treatment subdivided into six replicates of 12 chicks. The first treatment is a control group, and the second and third are basic diets with 0.3% and 0.6% CO, respectively. Results: The 0.3% CO group had a higher final body weight, with no significant differences ( Conclusion: Adding 0.3% CO to the diet improves feed efficiency, lowers cholesterol, improves blood parameters, lowers inflammation, boosts antioxidant enzymes, and optimally improves intestinal structure, which is beneficial for poultry health and performance.
