The effects of castration (ram lambs versus wether lambs) on animal growth, feed efficiency, carcass characteristics, and cutability.

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
The aim of this experiment was to investigate the differences between intact (ram) and castrated (wether) lambs by evaluating animal growth pre- and post-weaning, feed efficiency, carcass characteristics, and carcass cutability. A total of 144 lambs were used for this feeding experiment (ram; n = 72 and wether; n = 72) and 70 lambs (ram; n = 35 and wether; n = 35) were slaughtered at the end of an 8-wk finishing period. Treatment (ram or wether) was randomly assigned shortly after birth. During the finishing period, lambs were weighed every 14 d. Lambs were slaughtered over five harvest dates based on live weight targets, evaluated for carcass characteristics 24-h postmortem, and fabricated into subprimal cuts 48-h postmortem, with weights collected from each subprimal. Results for the finishing period were analyzed using PROC MIXED in SAS with a fixed effect of sex with random effects of group (location and lambing season) and block. Carcass and economic value data were analyzed using PROC GLIMMIX in SAS with a fixed effect of sex and random effects of pen, block, and season. In terms of animal growth, there was a sex × time interaction (
