Prevalence and prognostic implications of the no-reflux phenomenon in patients undergoing primary percutaneous coronary intervention at a university center in a middle-income country.

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
objectiveTo analyze the prevalence of no-reflow and the 30-day mortality in a university center in a middle-income country.
methodWe analyzed 2463 patients who underwent primary PCI from January 2006 to December 2021. The outcome measure was 30-day mortality.
resultsOf a total of 2463 patients, no-reflow phenomenon was found in 413 (16.8%) patients, 30-day mortality was 16.7 vs. 4.29% (p < 0.001). Patients with no-reflow were older 60 (53-69.5) vs. 59 (51-66) (p = 0.001), with a higher delay in onset of symptom to emergency department arrival 270 vs. 247 min (p = 0.001). No-reflow patients also had had fewer previous myocardial infarction, 11.6 vs. 18.4 (p = 0.001) and a Killip class > 1, 37 vs. 26% (p < 0.001). No-reflow patients were more likely to have an anterior myocardial infarction (55.4 vs. 47.8%; p = 0.005) and initial TIMI flow 0 (76 vs. 68%; p < 0.001).
conclusionNo-reflow occurred in 16.8% of STEMI patients undergoing primary PCI and was more likely with older age, delayed presentation, anterior myocardial infarction and Killip class > 1. No-reflow was associated with a higher mortality at 30-day follow-up.
