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
Porcine reproductive and respiratory syndrome (PRRS), caused by PRRS virus (PRRSV), leads to severe economic losses in the pig farming industry. Currently, there is no specific treatment for PRRSV. This study investigated the epidemiological characteristics of PRRSV in large-scale pig farms across 24 provinces and municipalities in China from 2020 to 2023. Subsequently, serum acclimatization of gilts was implemented in large-scale pig farms to evaluate its impact on the reproductive performance of sows and the growth performance of piglets. The results showed that 14 provinces had PRRSV-positive rates exceeding 10%, with Yunnan Province reporting the highest rate at 23.5%, whereas Zhejiang had the lowest at 3.5%. The PRRSV-positive rate exhibited clear seasonality, with markedly higher rates in winter and spring compared to summer and autumn. The introduction of gilts was identified as the most important cause of PRRS outbreaks, with an incidence rate as high as 49%. Following serum acclimatization, the average total number of piglets per litter, the average number of live piglets per litter, the number of piglets weaned per litter, and the total weaning weight per litter were all significantly higher than those before acclimatization and in unacclimated sows (
