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

Due to the lack of reliable epidemiological information regarding the geographic distribution and genetic diversity of human polyomaviruses (HPyV) in Portugal, we addressed these issues in this initial study by focusing on the Lisbon Metropolitan area, the most populated and culturally diverse hub in the country. The HPyV structural protein-coding sequence was partially amplified using two touch-down PCR multiplex protocols, starting from water samples, collected between 2018 and 2020, where viral genomes were detected. The obtained results disclosed the frequent detection of HPyV1, HPyV2, HPyV5, and HPyV6 in 35.3% (
