Geographic Variation in Door-to-Needle Time among Patients with STEMI from the Metropolitan Region of Rio de Janeiro: Results of the EQUITY-MI Cohort.

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
backgroundThere is a gap in information regarding the reperfusion strategies used and the evolution of patients with ST-segment elevation myocardial infarction (STEMI) in the state of Rio de Janeiro.
objectiveTo assess thrombolysis time in the diverse regions of the state capital and metropolitan area of Rio de Janeiro, as well as the outcome of post-infarction heart failure.
methodsEQUITY-MI is a prospective cohort study of patients diagnosed with STEMI and referred to a single reperfusion center. Continuous variables were analyzed using the Kruskal-Wallis test, and categorical variables were analyzed using the chi-square test. In order to estimate the effect of door-to-needle time (DNT), generalized linear regression models with gamma distribution and log link function were applied, in addition to quantile regression to estimate the effect at the 25%, 50%, and 75% quantiles, both adjusted for sex, age, race, and education level. The significance level applied was 0.05.
resultsThe study included 457 patients, with a mean age of 60.4 years, 79% of whom received thrombolysis, with a median DNT of 77 minutes, and 20.9% were thrombolyzed within 30 minutes, with no statistical difference between regions (p = 0.23). The Baixada Fluminense region presented the highest adjusted mean DNT (165.9 minutes), with a time difference compared to the North Zone (0.61; 0.44 to 0.87; p = 0.003) and West Zone (0.69; 0.51 to 0.96; p = 0.022). It also presented the highest DNT in all intervals (Q25, Q50, Q75). After infarction, 63.5% of patients presented heart failure.
conclusionThere was a general delay in DNT for patients included in the EQUITY-MI study, with worse systematic performance in the Baixada Fluminense region, in addition to a high incidence of post-infarction heart failure.
