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: Blood pressure variability (BPV) is recognized as an independent risk factor for cardiovascular morbidity and mortality. However, findings regarding the association between the coefficient of variation (CV) of 24-h blood pressure and mortality in patients with acute myocardial infarction (AMI) remain inconsistent. The aim of this study was to examine the association between 24-h CV and the risk of in-hospital, 30-day, 1-year, and 3-year mortality in AMI patients. Methods: This retrospective cohort study included AMI patients who were admitted to the intensive care unit (ICU) from the MIMIC-IV 2.0 database. The CV was calculated from blood pressure measurements taken during the first 24 h. Patients were divided into three groups according to tertiles of 24-h blood pressure CV. The relationship between 24-h CV and the risk of all-cause mortality in AMI patients was analyzed using logistic regression, Cox proportional hazards regression, and Kaplan-Meier survival analyses. Results: A total of 1291 eligible AMI patients were included. Compared with Q1 (lowest CV), Q3 (highest 24-h systolic blood pressure [SBP]-CV) was significantly associated with an increased risk of in-hospital (odds ratio [OR]: 3.333, 95% confidence interval [CI]: 1.725-6.439), 30-day (hazard ratio [HR]: 1.868, 95% CI: 1.201-2.904), and 1-year (HR: 1.420, 95% CI: 1.058-1.907) mortality. Both Q2 and Q3 of 24-h diastolic blood pressure (DBP)-CV were significantly associated with an increased risk of in-hospital, 30-day, 1-year, and 3-year mortality. Kaplan-Meier survival curves demonstrated that patients in Q3 had significantly lower 30-day, 1-year, and 3-year survival probabilities than those in other tertiles for both SBP and DBP. Conclusions: Our findings suggest that 24-h SBP-CV and DBP-CV are significantly associated with both short- and long-term outcomes in AMI patients. BPV may serve as a prognostic marker for all-cause mortality in AMI patients.
