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
This study investigates differences in reproductive performance, testicular histology, and transcriptomic profiles between male Subei (SB; semi-wild) yaks and two domestic yaks, Gannan (GN) and Qinghai (QH). Key metrics including mating age, utilization time, breeding capacity, morphometric traits, and testicular indices were analyzed. SB yaks exhibited superior reproductive metrics, including earlier sexual maturity, prolonged utilization periods, and enhanced breeding capacity compared to GN and QH (P < 0.05). Morphologically, SB yaks demonstrated significantly greater body weight, and testicular dimensions. Compared with GN and QH yaks, the seminiferous tubules of SB yaks exhibited significantly larger spermatogenic cells and luminal cavities, along with a notably higher sperm density within the luminal cavity. Transcriptomic analysis identified 2,403 and 4,428 differentially expressed genes (DEGs) in GN vs. SB and QH vs. SB comparisons, respectively. Eight key genes (TPPP3, SMAD3, PAFAH1B3, BMP7, ARSA, CTNNB1, SMAD4, STAT3) and three pathways (Hippo, pluripotency regulation, TGF-β) were implicated in testicular development and spermatogenesis. These findings underscore the genetic and physiological advantages of SB yaks, offering insights for enhancing male yak reproductive performance.
