Fragmented QRS and QRS Duration As a Marker of Myocardial Reperfusion Measured by Myocardial Blush Grade in Reperfusion Therapy: Systematic Review and Meta-Analysis.

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
Myocardial blush grade (MBG) is an indicator of microvascular perfusion and patency and an independent predictor of cardiac outcomes. QRS duration and fragmented QRS (fQRS) before reperfusion and its changes after reperfusion are shown to be associated with MBG. We aimed to assess the latest evidence on the association between fQRS and QRS duration with MBG in reperfusion therapy. We performed a comprehensive search on the association between fQRS and QRS duration in successful/impaired reperfusion measured by MBG. There were a total of 1,311 patients from six studies. A shorter QRS duration immediately and at 60 minutes after reperfusion attempt was associated with successful reperfusion, with a mean difference (MD) of -10.62 ms ([-15.55, -5.70];
