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
Heat stress is a major environmental constraint compromising poultry productivity, welfare, and health in tropical regions. This study evaluated the adaptive responses of five duck genotypes, including local Rupali, a BLRI-improved common duck with white plumage; Pekin, an exotic duck; F1, a crossbred (two-way crossing: Pekin ♂ x Rupali ♀); Muscovy duck, an exotic and H1, the first hybrid (three-way crossing: Muscovy ♂ x Pekin ♂ x Rupali ♀) under heat stress in tropical Bangladesh. A total of 200 ducklings (40 ducklings/genotype) were used in the study and allocated into 4 replicate groups per genotype (10 ducklings/group) housed in individual pens. The ducklings were exposed to elevated temperature in a controlled environmental chamber for 21 days. Respiration and panting rate, skin and rectal temperature, plasma corticosterone, immunological Y and M (IgY, IgM), cholesterol, triglycerides (TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL), alanine aminotransferase (ALT), aspartate aminotransferase (AST), hemoglobin (Hb), heterophil to lymphocyte ratio (H/L ratio), white and red blood cells (WBC and RBC) count parameters were assessed at baseline (day 21), during acute heat stress (day 35), and after prolonged heat stress (day 42) period. Significant genotypic differences were observed in heat tolerance. H1 hybrid ducks exhibited comparatively balanced physiological and biochemical responses relative to the exotic genotypes under heat stress. These findings suggest that heterosis in H1 ducks may support partial metabolic stability and adaptive responses under heat stress conditions. The results support the potential use of H1 hybrids to enhance sustainable duck production in tropical environments.
