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.
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
The objective of the present study was to determine the effects of dietary supplementation of graded levels of coffee by-products (CBP) on growth performance, gut health, and toxicity in broiler chickens. A total of 60 (14 days old) Cobb 500 broiler chickens were used in this experimental study. The three treatment diets were prepared with 0%, 1.5% and 2.5% CBP in a complete randomized experiment. There were no differences in total feed intake (TFI) across treatments (P > 0.05). However, chickens fed diets with 2.5% CBP had lower total weight gain (TWG) and higher feed conversion ratio (FCR) compared to those on the control and 1.5% CBP diet (P < 0.05). High digestibility coefficient values for dry matter (DM), crude protein (CP) and crude fibre (CF) were observed in chickens fed control diets compared to chickens fed diets with 1.5% and 2.5% CBP (P < 0.05). Broilers fed diets with 1.5% CBP diets had higher dressing percentages and relative weights for breast than those on the control diet (P < 0.05). Hepatic cells and sinusoidal morphological arrangement were normal across all treatments. Additionally, broilers fed 2.5% CBP exhibited longer intestinal villi compared to those on the control diet. It can, therefore, be said that optimal performance can be attained by incorporating 1.5% CBP in broiler diets without any detrimental effects.
