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
Background: Coronary artery perforation is a rare but life-threatening complication of percutaneous coronary intervention. We present a case of coronary artery perforation treated with a PK Papyrus covered stent. Neointimal coverage evaluation was performed using optical coherence tomography (OCT) and coronary angioscopy (CAS) at 3 and 9 months after stent implantation. Case summary: A 63-year-old man was admitted to our hospital with worsening effort angina over 3 months. Coronary angiography revealed severe stenosis in the proximal segment of the left anterior descending artery. After stent implantation, coronary artery perforation occurred. We immediately sealed the perforation site using a PK Papyrus covered stent. The patient was discharged on postoperative day 4. OCT and CAS revealed incomplete neointimal coverage at the PK Papyrus covered stent strut 3 months after stent implantation. At 9 postoperative months, complete neointimal coverage was observed. We continued clopidogrel and edoxaban, but no clinical adverse events were encountered during the follow-up. Discussion: To the best of our knowledge, this is the first report of a serial observation of PK Papyrus covered stent implantation for coronary artery perforation using OCT and CAS. In this case, OCT and CAS revealed complete neointimal coverage, without obvious thrombus, 9 months after PK Papyrus implantation. Based on the OCT and CAS findings, our report presents an appropriate follow-up strategy for the prevention of stent thrombosis when using a PK Papyrus covered stent, which will contribute to future research on the appropriate duration of dual antiplatelet therapy and evaluation of neointimal coverage.
