Five-year clinical outcomes of zotarolimus-eluting stents in coronary total occlusions.
Article in EuroIntervention : journal of EuroPCR in collaboration with the Working Group on Interventional Cardiology of the European Society of Cardiology, 2021. 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
aimsReports of long-term outcomes of patients treated with drug-eluting stents in total coronary occlusions are limited. We analysed clinical outcomes of patients treated with the zotarolimus-eluting Resolute stent (R-ZES) implanted in coronary total occlusions versus non-occluded lesions. METHODS AND
resultsPatients treated with R-ZES and included in four trials (RESOLUTE All Comers, RESOLUTE International, RESOLUTE China RCT, and RESOLUTE China Registry) were pooled and divided into three groups - patients with chronic total occlusions (CTO), patients with total occlusions that had occurred recently (rec-TO), and patients without total occlusions (non-TO). Clinical outcomes at five years were analysed. Of 5,487 patients treated with R-ZES in these trials, 8.0% had CTOs, 8.5% rec-TOs and 83.5% non-TOs. Patients had a mean age of 62.8 years, approximately 25% were female and 30% were diabetics. TLF was similar in the three groups at five years (TLF was 13.2%, 12.5% and 13.3% in the CTO, rec-TO and non-TO groups, respectively, p=0.96). Stent thrombosis tended to occur more frequently for rec-TO compared to CTO and non-TO patients (2.6% vs 1.2% and 1.3%, respectively, p=0.11).
conclusionsIn this large population of patients who had R-ZES implanted, five-year clinical outcomes were similar whether or not the stents were implanted in total occlusions.
