1 · What the graph read from it

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.

2 · The registry

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

What is already known about this topic?: Mpox transmission occurs primarily through close skin-to-skin contact, sexual contact, and exposure to contaminated materials; imported cases can establish local transmission clusters in settings characterized by high international mobility. What is added by this report?: This report documents the first identified cluster of mpox virus Clade Ib infections in Yiwu, China, an international trade hub. A total of six laboratory-confirmed cases were identified between July 23-August 6, 2025, including one imported source case from Tanzania and five locally linked secondary cases. Among 43 environmental samples, 27 (62.8%) tested positive for MPXV DNA. Ninety close and general contacts were traced and monitored under 21-day health surveillance, with no additional infections detected. We also report a case with oropharyngeal PCR positivity prior to rash onset, suggesting potential pre-symptomatic viral shedding. What are the implications for public health practice?: Rapid multi-agency collaboration encompassing case identification, isolation protocols, contact tracing, and environmental decontamination proves effective for interrupting transmission in international trade hubs; targeted surveillance and proactive outreach to high-risk social and sexual networks remain essential components of outbreak control.
