Use of Doppler Ultrasound for Saphenous Vein Mapping to Obtain Grafts for Coronary Artery Bypass Grafting.
Trial report in Brazilian journal of cardiovascular surgery. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
introductionThe great saphenous vein is widely used as a graft in coronary artery bypass grafting surgery. Complications due to saphenous vein harvesting can be minimized when using ultrasonography mapping and marking.
objectiveTo analyze by clinical trial the use of vascular ultrasonography to map the saphenous vein in coronary artery bypass grafting to determine viability and dissection site.
methodsA total of 151 consecutive patients submitted to coronary artery bypass surgery with the use of the great saphenous vein as a graft were selected for this prospective study. They were divided into two groups: Group 1 - 84 patients were submitted to ultrasonographic mapping and marking of the saphenous vein; Group 2 - 67 patients had saphenous vein harvested without any previous study. Both groups were coupled with follow-up on the 1st, 5th and 30th postoperative days. Primary endpoints were need for incision of the contralateral leg and wound complications within 30 days.
resultsBoth legs had to be incised in 6 (8.95%) patients from Group 2 (P=0.0067). Wound complications occurred in 33 (23.4%) patients within 30 days, 21 (35%) from Group 2 e 12 (14.8%) from Group 1 (OR 3.095, 1.375-6.944, CI 95%, P=0.008). Within 30 days there were 4 (2.8%) deaths, all in Group 2 (P=0.036).
conclusionThe use of vascular ultrasonography for mapping of the great saphenous vein in coronary artery bypass surgery has properly identified and evaluated the saphenous vein, significantly reducing wound complications and unnecessary incisions. It would be advisable to use this noninvasive and easy to use method routinely in coronary artery bypass surgery.
