Sex and Medium-term Outcomes of ST-Segment Elevation Myocardial Infarction in Kerala, India: A Propensity Score-Matched Analysis.
Article in CJC open, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 2 of them syntheses that pooled it.
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
backgroundSex-based differences have been found in outcomes following ST-segment myocardial infarction (STEMI). Studies assessing sex-based differences in STEMI among Indian patients have reported conflicting results.
methodsA prospective multicenter registry of consecutive patients with STEMI who presented to percutaneous coronary intervention (PCI)-capable hospitals in the Indian state of Kerala between June 2013 and March 2017 was used to assess 1-year outcomes. The primary endpoint was a composite of major adverse cardiac events (MACE), including death, stroke, nonfatal myocardial infarction, and rehospitalization for heart failure. Outcomes of 2 sex-based propensity score-matched groups were compared.
resultsWe included 3194 patients (19.4% women). Women presenting with STEMI were older, had more traditional cardiovascular risk factors, and were more likely to be classified as living in poverty. After propensity-score matching, women experienced greater incidence of MACE (20.9% vs 14.3%,
conclusionsWomen in this cohort experienced higher incidence of MACE at 1 year, compared to men, primarily owing to increased mortality. Timeliness of reperfusion appears to be the primary factor impacting differences in outcomes between the 2 groups and may represent an attractive target for quality-improvement initiatives.
