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
Guinea pig (Cavia porcellus) production represents an important source of high-quality animal protein in Andean regions, however knowledge regarding the evolution of carcass characteristics and meat quality parameters during the growth period is limited. This study investigated the progression of carcass traits, regional composition, linear measurements, pH and color evolution during muscle-to meat conversion, and non-carcass components in Peru breed guinea pigs at three critical ages: 3, 4, and 6 months. A total of 120 animals (20 males and 20 females per age group) were evaluated following standardized slaughter and carcass evaluation protocols. Results demonstrated significant age-dependent increases in live weight at slaughter, empty body weight, and hot and cold carcass weights. Males exhibited higher values than females across all weight parameters. Regional composition analysis revealed proportional changes in shoulder and neck (in females) and long leg and ribs (in males) percentages with advancing age. Linear measurements showed progressive increases in all carcass dimensions, with carcass compactness indices improving significantly from 3 to 6 months. Post-mortem pH evolution in Longissimus thoracis and Psoas major muscles followed expected glycolytic patterns. Color parameters exhibited distinct temporal and age-related variations, with younger animals showing more pronounced changes during the muscle-to-meat conversion process. Non-carcass components evaluation demonstrated allometric growth patterns relative to body size, with peri-renal fat deposition increasing substantially between 3 and 6 months. These findings provide essential baseline results for optimizing slaughter age decisions and understanding meat quality development in guinea pig production systems, contributing to the standardization of carcass evaluation protocols for this emerging livestock species.
