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
backgroundAsiatic mouflon (Ovis gmelini) consists of several subspecies mainly distributed in Armenia, southern Azerbaijan, Cyprus, northern, southern, and western regions of Iran, and eastern and central regions of Turkey nowadays. Genome analyses of Asiatic mouflon in Iran revealed that they could have diverged from the direct ancestor of domestic sheep, and showed genetic introgression into domestic sheep after domestication. However, the impact of the Asiatic mouflon subspecies in Iran on sheep domestication remains unclear.
resultsHere, we conducted a comprehensive population genomics analysis of Asiatic mouflon in Iran with 788 whole-genome sequences (including 40 from Asiatic mouflon), 1104 whole mitogenomes (105 from Asiatic mouflon), and 239 Y chromosomes (21 from Asiatic mouflon). Whole-genome sequence analyses revealed two subpopulations of Asiatic mouflon in Iran: O. gmelini_2 limited on Kaboodan Island in Urmia Lake National Park and O. gmelini_1 over a wide geographic area. Phylogenetic analyses of Asiatic mouflon in Iran based on uniparental variants revealed a monophyletic lineage with the mitochondrial haplogroups C/E, and clustered into a monophyletic with Y-chromosomal lineage HY2 of sheep. Additionally, introgression tests detected significant signals of genetic introgression from O. gmelini_2 to four sheep populations (e.g., Garut, Bangladeshi, Nellore, and Sumatra) in South and Southeast Asia. In the four sheep populations, selective tests and introgression signals revealed that the wild introgression could have contributed to their body size, fat metabolism and local adaptation to the hot and humid environments in the Indian Peninsula.
conclusionsOur results clarified subpopulation structure of Asiatic mouflon in Iran, identifying two distinct groups: O. gmelini_1 and O. gmelini_2. Additionally, we suggest a potential genetic contribution to domestic sheep by introgression, with maternal haplogroup C and paternal lineage HY2 likely originating from the Asiatic mouflon populations in Iran. Our findings offer new insights into domestication of sheep and subsequent introgressions events from wild relatives to domestic populations.
