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
backgroundSeveral studies have shown that women are usually undertreated and have worse outcomes after ST-segment elevation myocardial infarction (STEMI), hence the need to investigate questions related to sex in Brazil to better deal with the problem.
objectiveTo determine whether female sex is still associated with adverse events in a contemporary cohort of patients with STEMI undergoing primary percutaneous coronary intervention (pPCI).
methodsThis was a prospective cohort study of STEMI patients submitted to pPCI in a tertiary university hospital between March 2011 and December 2021. Patients were categorized into groups based on their sex at birth. The primary clinical outcome was long-term MACCE. Patients were followed-up for up to five years. All hypothesis tests had a two-sided significance level of 0.05.
resultsAmong 1457 patients admitted with STEMI in the study period, 1362 were included and 468 (34.4%) were women. Female patients had a higher prevalence of hypertension (73% vs. 60%, p <0.001), diabetes (32% vs. 25%, p=0.003) and Killip class 3-4 at hospital admission (17% vs. 12%, p=0.01); TIMI risk score was higher among women (4 [2, 6] vs. 3 [2, 5], p<0.001). In-hospital mortality was not different between groups (12.8% vs. 10.5%, p=0.20). In-hospital MACCE (16.0% vs. 12.6%, p=0.085) and long-term MACCE (28.7% vs. 24.4%, p=0.089) were numerically higher in women, with borderline significance. After multivariate analysis, female sex was not associated with MACCE (HR = 1.14; 95% CI 0.86 - 1.51; p = 0.36).
conclusionIn a prospective cohort of STEMI patients submitted to pPCI, female patients were older and had more comorbidities at baseline, but no significant differences were found in terms of long-term adverse outcomes.
