Long term outcomes after COVID-19 in patients with schizophrenia: a historical cohort study in a health maintenance organization.

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
backgroundSevere mental illness may affect health behaviors and outcomes during pandemics. Few studies have assessed whether people living with schizophrenia spectrum disorders (SSD) experienced adverse COVID-19 outcomes.
methodsIn a population-based historical cohort study comprising members of a health maintenance organization, we included 1273 patients with SSD and 12,730 age- and sex-matched controls tested for SARS-CoV-2 between March 2020 and May 2022. We assessed the association between schizophrenia and hospitalization, hospital length-of-stay, 30-day, and one-year mortality, constructing multiple linear regression and logistic regression models adjusting for sociodemographic factors, BMI, smoking, number of comorbidities, and vaccinations. We also assessed whether vaccination modified the association between schizophrenia and mortality.
resultsAmong patients with SSD, 477 (37.5%) had a positive test, compared to 6203 (48.7%) in the comparison group. patients with SSD were at increased risk of hospitalization (adjusted odds ratio (OR
conclusionsIn our cohort, patients with SSD experienced a significantly higher rate of hospitalization, length of stay, and mortality following a positive SARS-CoV-2 test, even after adjusting for important prognostic factors. COVID-19 vaccination modified these risks.
