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

backgroundSerological assays for the determination of the immune status of patients that have tested positive for infection with SARS-CoV-2 by RT-PCR are required for, e.g., contact tracing and epidemiological studies. However, data concerning the performance parameters of commercially available high-throughput ELISA tests are still not available on a large scale. STUDY

designIn our study, we have evaluated an in-house developed ELISA for the detection of the immunoglobulin classes A, G and M directed against the full-length spike glycoprotein from SARS-CoV-2. For this analysis, we have included 110 sera from patients presenting with COVID-19 symptoms or blood donors without symptoms collected at the Austrian Red Cross, Blood Transfusion Service for Upper Austria, Linz. In addition, we have selected four commercially available IgG-based ELISAs as well as one IgA/IgG-based ELISA for the detection of SARS-CoV-2 antigens as well as a multiplexed IgG-based micro-ELISA assay developed for rapid Point of Care testing applications.

conclusionsAll assays evaluated in the course of this study demonstrated suitable sensitivity and specificity values for the identification of patients that have experienced a past infection with SARS-CoV-2. However, testing for the presence of additional immunoglobulins (IgA and IgM) as well as using combinations of different viral antigens is highly advised to improve the predictive values of serological assays.
