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

Use of antigen tests for the diagnosis of COVID-19 has become widespread. The aim of this study was to evaluate the diagnostic accuracy of the nasopharyngeal rapid antigen diagnostic (RAD) immunoassay LumiraDx UK in an Emergency Department (ED). All patients admitted to our ED between November 11 and December 8, 2020, and had both a RAD test and a real-time-reverse-transcription-polymerase-chain-reaction (RT-PCR) test were enrolled. RAD was considered as the index test and RT-PCR test was used as the reference standard. Sensitivity, specificity, negative and positive predictive values, and likelihood ratios were calculated with the 95% confidence interval. The sensitivity and specificity of RAD were 34.2% and 92.3%. Positive and negative likelihood ratios were 4.4 and 0.71. Our results demonstrate that the diagnostic accuracy of the LumiraDx RAD test is too low for routine use as a diagnostic method in the ED.
