Evaluation of feed withdrawal prior to marketing to improve carcass yield and reduce feed cost in finishing pigs.

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
Fasting pigs prior to harvest benefits food safety and pork quality. Studies have examined the effect of feed withdrawal prior to marketing applied on groups of pigs marketed at one time but not across multiple marketing events. Therefore, this study determined the effects of three feed withdrawal times before the first and final marketing event on pig performance, carcass traits, and economic return. A total of 695 finishing pigs (117.6 ± 1.06 kg) were allotted in a randomized complete block design and assigned to 1 of 3 treatments (24 pens per treatment; 9 to 10 pigs per pen). Treatments consisted of 12, 18, or 24 h (including transportation and lairage) of feed withdrawal prior to harvest to determine its effects on hot carcass weight (HCW), carcass yield, and economic costs vs. benefits of pigs marketed at two different marketing events (3 heaviest pigs per pen marketed 14-d prior to the final marketing of all remaining pigs). There were no differences in growth performance during the 14-d period between marketing events. However, pigs with 24 h of feed withdrawal prior to harvest had lower (
