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

Since the COVID-19 pandemic, functional non-neutralizing antibody responses to SARS-CoV-2, including antibody-dependent cell-mediated cytotoxicity (ADCC), are poorly understood. We developed an ADCC assay utilizing a stably transfected, dual-reporter target cell line with inducible expression of a SARS-CoV-2 spike protein on the cell surface. Using this assay, we analyzed 61 convalescent serum samples from adults with PCR-confirmed COVID-19 and 15 samples from healthy uninfected controls. We found that 56 of 61 convalescent serum samples induced ADCC killing of SARS-CoV-2 S target cells, whereas none of the 15 healthy controls had detectable ADCC. We then found a modest decline in ADCC titer over a median 3-month follow-up in 21 patients who had serial samples available for analysis. We confirmed that the antibody-dependent target cell lysis was mediated primarily via the NK FcγRIIIa receptor (CD16). This ADCC assay had high sensitivity and specificity for detecting serologic immune responses to SARS-CoV-2.
