Early Detection of Porcine Reproductive and Respiratory Syndrome Virus Outbreak: Combination of Methods.
Article in Veterinary sciences, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 current application of the production data exponentially weighted moving average (EWMA) model can detect PRRSV outbreaks earlier than that of processing fluid (PF) testing; however, its advantages have not been fully reported. This study aimed to analyze various production parameters, including abortion, off-feed, low appetite, and dead sows, on a daily basis following a PRRSV outbreak in an II-vx sow farm. The EWMA method was employed and the results were compared with the early detection of positive PF results. Differences in daily abnormal indicators across the three PRRSV status periods were analyzed. Additionally, this study evaluated the PRRSV detection rates in different sample types (AF, OS, and TBS) from aborted sows and compared the detection rates of different sample combinations using statistical tests. The 187-day study revealed that the first true positive (TP) alarm point for daily abortion sows occurred on day 107 and for off-feed sows on day 110. In contrast, the first RT-qPCR-positive result for PF was obtained on Day 122. The average values of daily abortions and off-feed sows in status I-A were significantly higher than those in status II-vx and I-B. Conversely, the average value of low appetite in status I-A was significantly lower than that in statuses II-vx and I-B. No significant differences were observed in the daily number of dead sows among the three groups. The RT-PCR detection rates varied significantly (
