Using a SPOT ROI Function to Minimize Radiation During Chronic Total Occlusion Percutaneous Coronary Interventions.
Article in JACC. Case reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectiveThis study highlights a case in which we performed a complex percutaneous coronary intervention on a 60-mm chronic total occlusion lesion with a remarkably low radiation dose by using the SPOT region of interest (SPOT ROI) function available on the Alphenix Evolve Edition X-ray system (Canon Medical Systems). KEY STEPS: Fluoroscopy was conducted exclusively using SPOT ROI from the start of guiding catheter engagement. The wire successfully traversed the chronic total occlusion lesion with SPOT ROI. Despite a fluoroscopy time of 71 min, the total radiation dose was kept at 990 mGy, remaining <1 Gy. POTENTIAL PITFALLS: The SPOT ROI function is only available on the Alphenix Evolve Edition X-ray system and cannot be used with other X-ray equipment. TAKE-HOME MESSAGE: This case suggests that SPOT ROI can be leveraged to safely reduce radiation during complex percutaneous coronary intervention.
