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

Inborn errors of type I IFN (IFN-I) immunity and neutralizing autoantibodies (auto-Abs) against IFN-I (AAN-I-IFNs) impair antiviral immunity and underlie critical COVID-19. Their impact on disease severity in different populations, such as Latin American populations, remains to be better understood. This study assessed the presence of AAN-I-IFNs (anti-IFN-α2, anti-IFN-ω, and anti-IFN-β) in a cohort of 458 COVID-19 patients from southern Brazil, stratified as mild (n = 224) versus non-mild (n = 234), or survivors (n = 369) versus deceased (n = 89). AAN-I-IFNs were detected in 17 patients (3.7%), with increasing prevalence across disease severity, present in one (0.4%) mild case and 16 (6.8%) hospitalized cases (P = 0.006); and eight (2.2%) survivors and nine (10.1%) deceased cases (P = 0.008). Anti-IFN-α2 and anti-IFN-ω auto-Abs were most frequently detected, while anti-IFN-β auto-Abs were found in one patient. Our findings highlight the role of AAN-I-IFNs underlying COVID-19 severity in a southern Brazilian population.
