Article in Emerging infectious diseases, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06784739 (COMMUNITY - the COVID-19 Immunity Study), which is not on this map. Cited by 7 papers, 1 of them a synthesis that pooled it.

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.

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.

Abstract

Given the recent surge in SARS-CoV-2 Omicron infections, we performed a quantitative PCR screening survey during June 28-29, 2022, in Stockholm, Sweden, to investigate SARS-CoV-2 point prevalence in a group with high exposure risk. Results showed SARS-CoV-2 infection in 2.3% of healthcare workers who were asymptomatic at time of sampling.
