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 this study was to evaluate the effects of dietary supplementation with nopal (Opuntia ficus-indica) on productivity, egg composition, and maternal–embryonic metabolism in laying hens under a family poultry production system. Forty-five Rhode Island Red hens were assigned to three treatments: a control diet or the same diet supplemented with 24 g fresh nopal/hen/day (forage, FN; vegetable, VN; ≈16.7% as-fed, ~ 2% DM) for 8 weeks after a 1-week adaptation period. Variables measured included feed intake, egg composition (protein, fat, carbohydrates, energy), maternal and chick serum cholesterol (0–12 h post-hatch), hatchability, embryonic mortality, and yolk sac utilization index (YSUI). Data were analyzed using mixed models considering treatment, period, phase, and interactions. Supplementation increased feed intake (FN: 118.78; VN: 106.18 vs. control: 90.47 g/hen/day), although body weight was lower than in the control. Egg composition was modified: FN showed higher fat content (6.58 g), whereas VN had lower values (6.48 g). Egg yolk cholesterol was higher in FN and VN (12.30 and 12.19 mg/g) compared to control (11.75 mg/g). Maternal serum cholesterol was highest in FN and control, and lowest in VN (125.44, 122.89, and 117.23 mg/dL, respectively). Chicks from VN exhibited greater post-hatch cholesterol reduction (36.45 mg/dL) and higher YSUI (3.12 vs. 2.02 and 1.45 in FN and control). In conclusion, nopal supplementation modulated maternal–embryonic metabolism, altered egg lipid composition, and improved yolk sac utilization efficiency, contributing to enhanced hatchability without compromising chick quality.
