Benign emergence of pathological Q waves following minimally invasive direct coronary artery bypass surgery: a case series.
Article in Journal of surgical case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
The development of new Q waves is an indicator of myocardial infarction following open coronary artery bypass grafting. It is unclear whether this is true for patients with multivessel coronary artery disease (MVD) treated initially with minimally invasive direct coronary artery bypass (MIDCAB). Electrocardiogram (ECG) changes were analyzed in a single center series of twenty-one consecutive patients with MVD undergoing MIDCAB. Six patients exhibited new Q waves in the inferior leads (group 1), 4 patients displayed significant QRS axis changes (group 2), and 11 patients presented with neither (group 3). The QRS axis and new Q waves reversed in most patients undergoing hybrid right coronary artery stenting and persisted in all patients receiving MIDCAB alone. In all cases, significant ECG changes were found to be benign and did not indicate myocardial infarction.
