1 · What the graph read from it

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.

2 · The registry

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

In the Hong Kong Special Administrative Region of China, there is a feral cattle population that has not been well characterized genetically. In this study, we used high-coverage (∼30×) whole-genome sequencing from 30 Hong Kong feral (HKF) cattle and compared them to 116 individuals from four representative populations worldwide. Our analyses revealed that the HKF cattle have high genetic diversity in the face of a declining effective population size, suggesting their substantial and yet untapped genetic potential. We also identified introgression events that occurred prior to the divergence between HKF cattle and other East Asian indicine populations, which shaped the adaptation of HKF cattle in Asian agro-ecologies. Moreover, we identified positive selection in HKF cattle for environmental adaptation, particularly in traits related to heat tolerance, bone strength, and coat color. Our findings provide insights into the genetic origin and unique adaptation of HKF cattle.
