No-Touch Saphenous Vein Graft vs Radial Artery as an I-Composite Graft From the Right Internal Mammary Artery.
Article in Annals of thoracic surgery short reports, 2026. 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
Background: As an inflow source for an I-composite graft, the right internal mammary artery (RIMA) can be a valuable option for anaortic off-pump coronary artery bypass grafting (OPCAB); however, the optimal extension graft from the in situ RIMA remains unclear. This study compared the suitability of the radial artery and no-touch saphenous vein graft as the extension graft from in situ RIMA. Methods: From January 2012 to February 2024, we performed isolated OPCAB with an I-composite RIMA graft on 208 patients at a single center. These patients were divided into the I-composite RIMA-radial (RAD group, 96 patients) and I-composite RIMA no-touch saphenous vein graft (NTSVG group, 110 patients) groups. The RAD and NTSVG groups were propensity score-matched (1:1, 73 patients each). Results: The RAD and NTSVG groups had 64 (66.7%) and 77 (70.0%) men (mean age, 62.7 [SD, 8.6] years and 65.0 [SD, 7.8] years) in the unmatched cohort and 51 (69.9%) and 50 (68.5%) men (mean age, 63.7 [SD, 8.2] years and 64.2 [SD, 7.8] years) in the matched cohort, respectively. After matching, Kaplan-Meier curves showed no significant difference in major adverse cardiac or cerebrovascular events ( Conclusions: The I-composite RIMA-RAD graft is an effective option for anaortic OPCAB in patients requiring multiple coronary revascularizations.
