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

Following the first detection of monkeypox virus (MPXV) clade Ib in Berlin, Germany, in December 2025, clade Ib rapidly predominated over clade IIb among notified mpox cases. The 35 clade Ib cases were primarily due to autochthonous transmission, with high genetic relatedness among strains circulating in men in Berlin, despite no identified epidemiological links. Sexual contact between men was reported as a potential source of infection in 28 cases, while for the remaining seven cases this information was unknown.
