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
Bovine coronavirus (BCoV) is an important viral agent associated with neonatal calf diarrhea (NCD), winter dysentery, and bovine respiratory disease, contributing to economic losses in cattle production worldwide. To date, BCoV sequence data from Yanbian, Northeast China, are limited in public datasets. In this study, we report the first successful isolation of a BCoV strain (BCoV-YBYJ) from a diarrheic calf in Yanbian using MDBK cells and characterize its replication in vitro and describe exploratory colon and lung findings following high-dose oral exposure in a murine model. The isolate replicated efficiently in MDBK cells. In mice, viral RNA was detected in the colon and lung with mild-to-moderate histological changes under high-dose exposure (nonnatural host). Phylogenetic analysis based on partial ORF1a, S, and M sequences showed that BCoV-YBYJ clustered with contemporary Chinese isolates within the available reference set, supporting regional genetic relatedness based on partial loci. In parallel, three SYBR Green I-based RT-qPCR assays targeting BCoV, bovine rotavirus (BRV), and bovine parvovirus (BPV) were established and analytically validated. These assays demonstrated satisfactory analytical sensitivity, specificity, and reproducibility within the validated dynamic range, and BCoV RNA was detected in 70% (140/200) of targeted diarrheic calf specimens (
