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
This case report describes the successful management of a complex percutaneous coronary intervention (PCI) in a 78-year-old man with a history of coronary artery bypass grafts. The patient presented with refractory angina symptoms and underwent PCI to the obtuse marginal (OM) vessel. The lesion proved to be balloon and microcatheter uncrossable and subsequent entrapment of a dislodged microcatheter tip, completely occluding vessel flow. Conventional retrieval methods failed, necessitating the use of the antegrade dissection and re-entry (ADR) technique with a Stingray balloon. This approach successfully recanalized the vessel, bypassing both the original lesion and the entrapped microcatheter tip. The case highlights the importance of advanced interventional strategies, typically associated with chronic total occlusion (CTO) interventions, in resolving complex coronary complications. It emphasizes the need for interventional cardiologists to be proficient in diverse techniques to address rare but potentially serious complications during PCI.
