Feasibility and long-term outcomes of recanalization for De novo small vessel chronic total occlusions.
Article in International journal of cardiology. Heart & vasculature, 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
Background: The impact of small vessel size on chronic total occlusions (CTO) interventions remains underexplored. We compared revascularization feasibility and follow-up outcomes between patients with small- and non-small vessel de novo CTOs. Methods: In total, 493 consecutive patients (64.0 ± 11.4 years, 432 men) undergoing wiring-based de novo CTO interventions were divided into two groups: small vessels (reference vessel diameter < 2.75 mm, Results: With increased J-CTO score, the procedural success rates remained comparable in the small vessel CTO group but declined significantly in non-small vessel CTO group when the score was ≥3 (82 vs. small vessel: 93%, Conclusion: Despite the longer guidewire crossing time for small vessel CTOs with higher complexity, we demonstrated greater procedural feasibility and better long-term TVMI-free survival for small vessel CTO interventions. However, long-term outcomes of small vessels can be clinically silent and therefore might affect the study results.
