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
Muscle traits are critical determinants of meat quality and productivity in sheep, influenced by both breed and anatomical region. Hanzhong sheep, an indigenous Chinese breed, are prized for tender, low-odor meat; yet, the molecular mechanisms underlying these traits remain poorly understood. In this study, we integrated meat quality assessment with metabolomic and transcriptomic profiling of the longissimus dorsi (HZ-B) and triceps brachii (HZ-T) muscles to elucidate biochemical and molecular bases of regional differences. The results, derived from metabolomic profiling, demonstrated that the muscle tissue of Hanzhong sheep contained abundant proteins (95 kinds) and fatty acids (150 kinds). The greater tenderness of HZ-B compared to HZ-T was associated with higher levels of dipeptides such as carnosine (FC = 1.07) and anserine (FC = 1.04), as well as upregulated expression of oxidative fiber-related genes MYH2 (FC = 2.92) and TPM1 (FC = 2.15). In contrast, HZ-T showed enrichment of flavor-associated metabolites, including acylcarnitines and glutamate, alongside higher expression of
