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 Aims: Delirium is a temporary cognitive dysfunction caused by organic factors. It is characterized by impaired attention and cognitive abilities. This condition is associated with a high prevalence of misdiagnosis and considerable risks of disability and mortality, particularly in intensive care unit (ICU) patients undergoing mechanical ventilation (MV). This study aimed to investigate the impact of the use of statins on the occurrence of delirium in patients undergoing MV in the ICU by applying a comprehensive data set. Methods: The Medical Information Mart for Intensive Care-IV (MIMIC-IV) database was used for participant recruitment. The primary outcome was the prevalence of delirium. Secondary outcomes were the duration of ICU stay (DoIS) and duration of hospital stay (DoHS). Multivariable logistic regression and multivariate linear regression were employed to carry out statistical analyses. Propensity-score matching (PSM) was utilized to enhance the robustness of findings. Statin use was determined based on patients' medication history before ICU admission. All the examinations and tests were conducted within 24 h after patients were admitted to the ICU. Results: The study comprised 18,146 participants with a mean age of 63.4 years and the prevalence of delirium was 7.6% (1381/18,146). According to multivariable logistic regression models, patients prescribed statins exhibited a 15% higher prevalence of delirium (odds ratio = 1.15, 95% confidence interval = 1.01-1.37, Conclusion: The findings of this retrospective cross-sectional study indicate that statin use is linked to an increased risk of delirium in patients receiving MV in the ICU.
