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
background and purposeThis study investigated the impact of schizophrenia on the outcomes of hospitalizations for acute ischemic stroke (AIS). Previous studies have suggested that outcomes are worse for patients with both AIS and schizophrenia, but a definitive conclusion is lacking.
methodsA retrospective analysis of the 2005-2020 United States Nationwide Inpatient Sample was conducted. Patients aged ≥20 years who were hospitalized for AIS were divided into two groups: with and without schizophrenia. The groups were matched using propensity-score matching at a 1:4 ratio. The assessed outcomes included in-hospital mortality, unfavorable discharge, length of hospital stay (LOS), and major complications. Logistic and linear regression analyses were used to assess outcome relationships.
resultsMatching resulted in 43,545 patients being analyzed: 8,709 with schizophrenia and 34,836 without schizophrenia. Schizophrenia was associated with higher risks of mortality (odds ratio [OR]=1.16), unfavorable discharge (OR=2.00), prolonged LOS (OR=1.61), and major complications (OR=1.39) including acute myocardial infarction, venous thromboembolism, pneumonia, sepsis, and acute kidney injury. Schizophrenia was also associated with higher total hospital costs (beta=6.73). The associations were consistent across most subgroups.
conclusionsSchizophrenia significantly worsens the outcomes in AIS patients, contributing to higher mortality, prolonged LOS, more complications, and increased hospital costs. These findings highlight the need to apply tailored management strategies to AIS patients with schizophrenia.
