Performance of the Sofia SARS-CoV-2 rapid antigen test as frontline test in a university hospital, Germany.

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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The rapid and reliable detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is of high importance for individual patient care and hospital infection prevention. We aimed to evaluate the performance of the Sofia SARS-CoV-2 antigen rapid diagnostic test (Ag-RDT) in comparison to real-time reverse-transcription polymerase chain reaction (RT-PCR). We conducted a prospective, monocentric cross-sectional study in an emergency department of a German university hospital from November 2020 to March 2021. We tested all samples using both Sofia SARS-CoV-2 Ag-RDT and real-time RT-PCR. A total of 7877 patients were included. Overall sensitivity of the Ag-RDT was 62.9% and specificity was 99.4%. Sensitivity varied across study months, whereas specificity remained high. Sensitivity increased to 94.2% in samples with a cycle threshold (Ct)-value ≤25. The Sofia Ag-RDT proved to be a rapid tool to detect samples with high viral loads (Ct-value ≤25) and might thus help to identify infectious patients.
