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/
objectivesSeveral studies in the literature support that endovascular aortic repair (EVAR) could exert a harmful effect on heart function, causing myocardial injury. The aim of this study is to investigate the correlation of high-sensitivity cardiac troponin I (hs-cTnI) levels during the immediate postoperative period after EVAR with various factors.
methodsA total of 104 patients were enrolled from February to December 2024 prospectively and consecutively. Patient demographics, cardiovascular comorbidities, laboratory tests, including hemoglobin and hs-cTnI levels, EVAR procedure duration and type of anesthesia were recorded. A generalized linear mixed model with a Gamma distribution and log link was fitted to analyze postoperative hs-cTnI concentrations across three time points (6 h, 24 h, and 48 h).
resultsThe mean age of patients was 71.6 ± 7.3 years, the mean transverse AAA diameter was 5.7 ± 1.1 cm and the mean preoperative hemoglobin was 14.2 ± 1.64 g/dL. In total, 72 patients received general anesthesia and 32 patients regional anesthesia. A total of 18 patients presented myocardial injury. Patients under general anesthesia had significantly higher mean hs-cTnI than those under regional anesthesia (
conclusionsGeneral anesthesia compared to regional anesthesia, older age, longer surgery, and higher baseline hs-cTnI are associated with higher postoperative hs-cTnI levels, while higher preoperative hemoglobin predicts lower hs-cTnI levels. Understanding the factors that are related to myocardial injury during EVAR could contribute to the improvement in procedures in order to minimize the harmful effect of EVAR on heart function.
