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
backgroundDuroc is one of the most popular terminal sire pig breeds worldwide due to its greater growth rate, meat quality, feed efficiency, and carcass characteristics compared to other breeds. Despite the breed's popularity, its developmental history, genetic diversity, and genetic relationships with other pig breeds remain largely unknown. Therefore, the primary objective of this study was to investigate population structure and genetic diversity of Duroc subpopulations from Europe, North America, and Australia, and of other pig breeds.
resultsThe studied pig populations were differentiated into five subgroups(European and North American Durocs, Australian Durocs, Asian-Pacific pig breeds, and two other breed groups [OBP1 and OBP2]), consistent with their geographical origins, as revealed by population structure analyses. The estimated effective population size (Ne) of Duroc subpopulations ranged from 17 to 47, while the Ne for the combined Duroc subpopulations was 172. A total of 140,713 runs of homozygosity (ROHs) were identified across all individuals, with 98,039 ROHs in Durocs and 42,674 in other pig breeds. Durocs had a greater number and proportion of longer ROHs (> 8 Mb) compared to other pig breeds. The ROH-based inbreeding (F
conclusionsSignificant differences exist in genetic diversity, population structure, and ancestry within Duroc subpopulations and between Duroc and other pig breeds. The observed inbreeding levels in Duroc subpopulations indicate the need for better management of genetic diversity within the breed. Functional enrichment analyses of shared ROH islands provide new insights into biological pathways shaped by selection decisions in the past decades, especially those related to the immune system and energy metabolism.
