Septal Collaterals in a Chronic Total Occlusion.
Article in JACC. Case reports, 2025. 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
objectivePercutaneous coronary intervention of a chronic total occlusion (CTO) should be considered in patients with angina or with documented ischemia. We present a patient with angina and stress echocardiography positive for ischemia in the anterior wall. KEY STEPS: The coronary angiography revealed a CTO in the left anterior descending artery, and a percutaneous approach was decided. The antegrade dissection reentry was unsuccessful. Retrogradely, through the ipsilateral septal collaterals, a SUOH wire was successfully advanced distally to the CTO. Externalization of the RG3 was successful, and the antegrade microcatheter was advanced inside the distal septal. Successful percutaneous coronary intervention of the left anterior descending artery was performed. POTENTIAL PITFALLS: Ping pong technique was not used, making the procedure challenging for equipment delivery. TAKE-HOME MESSAGES: One injection, one solution technique can be applied in selected cases with ipsilateral septal collaterals. Careful evaluation of the coronary anatomy before the procedure is mandatory.
