The association between previous SARS-CoV-2 infection and incidence of stroke.

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.
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
Objectives: To define the association between prior SARS-CoV-2 infection and incidence of stroke. Methods: We conducted a case-control study combining the Qatar stroke database and the Qatar National COVID-19 databases. Cases with stroke diagnosis were matched 1:1 on demographics, comorbidities, and vaccination status to controls who tested negative for SARS-CoV-2 during the same week. Adjusted odds ratios (aORs) comparing the odds of previous documented SARS-CoV-2 infection in cases relative to controls were estimated using conditional logistic regression. Results: Among 1640 matched pairs, 234 (14.3%) previous SARS-CoV-2 infections were recorded among cases and 399 (24.3%) among controls. The aOR (95% confidence interval [CI]) for the association of previous infection with stroke was 0.48 (0.40-0.58). Subgroup analyses revealed aORs of comparable magnitude among those aged 40-59 years and ≥60 years and those with or without coexisting conditions. Those unvaccinated (aOR 0.43; 95% CI 0.29-0.62), vaccinated with two doses (aOR 0.46; 95% CI 0.35-0.60), and vaccinated with three or more doses (aOR 0.63; 95% CI 0.42-0.96) all exhibited similar protective association of previous infection with stroke. Conclusions: Individuals with previous COVID-19 infection are less likely to develop stroke; this finding is not explained by demographic characteristics, comorbidities, or previous vaccination status.
