A unique stenosis in saphenous vein graft visualized by optical coherence tomography.
Article in Heart and vessels, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
We present a case of a unique stenosis in a 12-year-old saphenous vein graft (SVG), to the right coronary artery, which was visualized by optical coherence tomography (OCT), before percutaneous coronary intervention. The patient was an 80-year-old man in whom the stenosis was documented by area-detector coronary computed tomography. OCT imaging demonstrated that the culprit lesion was a venous valve containing a thrombus before preintervention imaging. Coronary stenting was performed with a distal protection device, and pathologic examination of the aspirate verified the OCT findings. Coronary angiography 12 years previously, just after coronary artery bypass surgery (CABG), had shown a completely normal SVG without any suspicion of a venous valve. These OCT images suggested the possibility that the culprit lesion was an "upside down" venous valve that was not visualized by angiography just after surgery, but could be a cause of late SVG stenosis following CABG. OCT imaging is very useful for clarifying the etiology of the stenosis in cases of ambiguous angiographic lesions.
