Internal thoracic artery grafting confers a survival benefit even in the most elderly population undergoing coronary artery bypass grafting.

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
Objective: Although the use of the left thoracic artery (LITA) is well accepted as the optimal conduit in coronary artery bypass graft surgery to improve survival, the survival benefit for the most elderly population is less well defined. Herein, we explore the lifetime benefit for use of the LITA versus saphenous vein grafting (SVG) only in a matched population of patients aged 80 years and older. Methods: Retrospective review was conducted of consecutive patients aged 80 years and older who underwent isolated coronary artery bypass graft procedures using either SVG only or ITA + SVG grafting between June 1982 and December 2011. Propensity score matching, logistic regression, Kaplan-Meier survival analysis, and Cox regression were used to examine perioperative and long-term survival outcomes. Results: There were 923 SVG patients and 1217 ITA + SVG patients. After propensity score matching there were 923 in each group. Follow-up ranged from 5 weeks to 25 years and was 99% complete. For matched patients, the operative mortality was 10.9% (101 out of 923) for SVG only and 7.8% (72 out of 923) ( Conclusions: Despite their advanced age and limited life expectancy, our data suggest that after adjusting for factors associated with selection bias, octogenarians enjoy long-term survival benefits from the use of ITA grafting.
