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
Mineral imbalances in livestock can severely impair growth, immunity, and productivity. Yaks inhabiting the Qinghai-Tibet Plateau face unique environmental challenges, including altitude-induced nutritional deficiencies. This study investigated the mineral status of healthy yak calves and its correlation with altitude across six regions in Ganzi Prefecture at elevations of 3200-4200 m, as well as the interrelationships among mineral elements in the "soil-forage-animal" ecosystem. A total of 42 hair samples and 42 serum samples were collected from yak calves across the six regions, and 49 forage samples and 49 soil samples were collected from seven regions. The contents of 11 mineral elements (Na, K, Ca, Mg, S, Cu, Fe, Mn, Zn, Co, and Se) were determined in all samples. The results revealed widespread deficiencies. The primary deficiencies were as follows: Na in hair was significantly lower than reference values, with deficiency rates ranging from 2% to 48.1%; Co was deficient to varying degrees in all samples, with deficiency rates ranging from 54.0% to 89.5%; Se was also commonly deficient, with rates between 32.7% and 74.7%. In serum, Mg, S, and Cu were generally deficient, with deficiency rates as high as 39.3%, 41.3%, and 47.2%, respectively. Serum Se deficiency occurred frequently at high altitudes, particularly in Seda and Shiqu counties. Additionally, significant correlations were observed: negative correlation between forage Zn and hair Zn in Luhuo, positive correlation between forage S and hair S in Ganzi, negative correlation between forage Se and serum Se in Yajiang, positive correlation between soil Se and forage Se as well as between soil Na and hair Na in Seda, positive correlation between forage Co and serum Co in Shiqu, and positive correlations between soil Se and serum Se and between forage Co and hair Co in Jiulong. These findings indicate that multiple mineral deficiencies are prevalent in yak calves, are closely associated with altitude, and may be influenced by soil and forage mineral composition as well as feeding practices. This study emphasizes the urgent need to develop targeted mineral supplementation strategies to support yak health and growth.
