Equalizing light and heavy litters with extra piglet relative to sow functional teats: impacts on lactational performance.
Article in Tropical animal health and production, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
This study evaluated the effects of litter equalization with different weights and numbers of piglets relative to the number of functional teats on sow and piglet performance during lactation. Litters (n = 183) were equalized based on weight (light: 0.955-1.289 kg; heavy: ≥ 1.399-1.935 kg) and piglet number by total number of functional teats (Eq-0: same number of piglets and teats; Eq + 1: one extra piglet than the teat number). Sow body condition was evaluated during lactation. Piglets were individually weighed and evaluated for face, body, and joint injuries. Females lost more caliper units in heavy litters (-0.39; P = 0.05), with no interaction with Eq-0 or Eq + 1 (P = 0.11). There was no difference in the total number of piglets weaned (P ≥ 0.08) regardless of litter weight, number of piglets by functional teats, or their interaction. Weaning weight and average daily gain were positively affected (P < 0.01) in heavy (6.1 ± 0.1 kg; 227.9 ± 0.3 g/d) compared to light litters (5.5 ± 0.1 kg; 214.0 ± 0.3 g/d). Mortality was not affected by different groups (P ≥ 0.60). However, the percentage of piglets removed before weaning was higher for Eq + 1 (5.21 ± 0.75%) than Eq-0 litters (2.66 ± 0.49%; P < 0.01). Heavy litters had a higher percentage of piglets with facial, body, and joint injuries compared to light litters, regardless of the number of piglets by functional teats. Equalizing litters with one extra piglet resulted in a higher pre-weaning piglet removal rate. Body parameters of sows were not compromised comparing Eq-0 and Eq + 1.
