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

backgroundAcute transverse myelitis (ATM) has been reported as a potential association between COVID-19 vaccination. In this study, we aimed to investigate the association between the COVID-19 vaccination and ATM.

methodsA self-controlled case series study was performed using a large database that combine the COVID-19 vaccine registry and the national claims database. The COVID-19 vaccination data included information on individuals aged 18 and above who received COVID-19 vaccination from February 26, 2021, to August 31, 2022. The claims database covered the entire Korean population for the period between January 1, 2002 to August 31, 2022. Patients who develop ATM within 1-42 days following COVID-19 vaccination were included. The observation period was 270 days after the first dose of the COVID-19 vaccine. The incidence rate ratio (IRR) and 95% confidence interval (CI) were estimated using a conditional Poisson regression model.

resultsA total of 159 ATM patients were included. Among them, 82 (51.6%) were male, and mean age was 55.4 (±17.4) years. The IRR was 2.41 (95% CI: 1.76-3.30) for the ATM risk within 1-42 days after COVID-19 vaccination. The IRR by vaccine product was 3.31 (95% CI: 1.81-6.05) for ChAdOx1-S; 1.99 (95% CI: 1.30-3.03) for BNT162b2; 2.57 (95% CI: 1.14-5.97) for mRNA-1273; and 3.33 (95% CI: 0.30-36.44) for Ad26.COV2.S.

conclusionThese findings indicated an increased risk of ATM following COVID-19 vaccination within 42 days. An association with the risk of ATM was found both for viral vector and mRNA vaccines.
