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: Psychological stress is increasingly recognized as an independent cardiovascular risk factor, yet its hemodynamic correlates in routine cardiology practice remain little characterized. In particular, the clinical implications of distinguishing between ongoing and previous stress have been seldom explored. Methods: This multicenter cross-sectional study was conducted across three cardiology outpatient clinics in Northern Italy. Between 2019 and 2025, a total of 675 consecutive adult patients undergoing their first outpatient evaluation were enrolled. Psychological stress was assessed through a structured physician-guided clinical interview and categorized as no stress, present stress, or previous stress. Blood pressure (BP), heart rate (HR), clinical characteristics, and lifestyle factors were recorded during the visit. Multinomial logistic regressions were used to identify determinants of stress timing and stressors, while linear regression models were used to evaluate associations between stress (present and previous) and cardiovascular parameters. Results: Overall, 373 patients (55%) reported psychological stress: 264 (39%) had present and 109 (16%) previous stress. Present stress was independently associated with younger age, female sex, lower physical activity, and anxiolytic treatment, whereas previous stress was independently associated with post-COVID enrollment. In multivariable linear regression models, present stress was independently associated with higher diastolic blood pressure (DBP) ( Conclusions: In cardiology outpatients, psychological stress is highly prevalent and shows distinct hemodynamic correlates according to its timing. Ongoing, but not previous, stress is independently associated with higher DBP, particularly among elderly, and patients with CAD. Routine assessment of psychological stress may improve cardiovascular risk stratification in outpatient practice.
