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

The level of neutralizing antibody (NAb) to SARS-CoV-2 could be used to evaluate the acquired protective immunity of COVID-19 patients or vaccinees. Here we develop a track-etched microporous membrane filtration microplate (TEM) and optical fibers transmitted immunosensing smartphone platform (TEMFIS) based surrogate virus neutralization test (TEMFIS-sVNT) for rapid one-step testing of NAb to SARS-CoV-2. Coefficient variation (CV) of intra-assay and inter-assay precisions of TEMFIS-sVNT varied below 9% or 14%, respectively. By agreement with pseudovirus neutralization test (pVNT) and ELISA-sVNT for testing of serum samples from 41 COVID-19 patients, 50 COVID-19 vaccinees and 320 healthy blood donors (P = 0.895), TEMFIS-sVNT detected the NAb positivity (sensitivity) in 92.68% COVID-19 patients and 76% vaccinees, but the NAb negativity (specificity) in 100% blood donors. In conclusion, TEMFIS-sVNT can be used for quantitatively point-of-care testing of neutralizing antibody to SARS-CoV-2 in blood samples from COVID-19 patients and vaccinees.
