COVID-19 diagnostic tests: Importance of the clinical context.
Review in Medicina clinica (English ed.), 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The current SARS-CoV-2 pandemic poses numerous health challenges, including the adequate use and proper interpretation of the different available tests in different clinical settings. As any diagnostic test, those of SARS-CoV-2 have methodological limitations of sensitivity (S) and specificity (E), which eventually determine their positive (PPV) and negative (NPV) predictive value. Furthermore, their diagnostic performance depends on the clinical context in which these tests are used, that is, on the pretest probability. This article: (1) reviews the main methodological aspects that influence the S, E, PPV and NPV of the most common SARS-CoV-2 diagnostic tests; and, (2) discusses its diagnostic interpretation in different clinical settings.
