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

We report a never seen before upsurge of Chlamydia pneumoniae (Cp) respiratory tract infections in 2024/25 in southern Germany. Regarding 43,558 Cp PCR tests analyzed, the positivity rate increased from 0.3% in 2015-2020 to 2.6% in 2024, and 2.4% in 2025 until August 2025, peaking at ≥ 6.0% with > 100 monthly cases in October and November 2024. Children aged 6-14 years were predominantly affected, and co-infections with other pathogens were frequently detected. We aim at raising awareness concerning Cp infections.
