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
Weaning age is a critical decision in beef cattle systems, ultimately influencing productivity and reproductive efficiency. This study investigated the productive performance of 152 Bonsmara cow-calf pairs under two distinct weaning practices: Early Weaning (EW) at 90 days and Conventional Weaning (CW) at 205 days. Data were obtained from the Arcadia Farmland cattle herd in the Vrede region of South Africa, comparing primiparous heifers with EW calves to a group of primiparous and second-time calving heifers with CW calves as a baseline comparison, reflecting limited research on EW in South Africa. EW calves received grower meal and natural grazing post-weaning, while CW calves depended on maternal milk and natural grazing. The farm's productive data indicated that CW achieved higher weaning weights per calf (+27 kg), highlighting productivity benefits. Conversely, EW reduced inter-calving periods (347 vs. 419 days), enhanced fertility, and improved herd reproductive efficiency, offering advantages in drought-prone settings. A General Linear Model (GLM) was applied to assess the influence of productive factors on 205-day calf weight. The model identified
