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: The influence of socioeconomic status on the decision to use bilateral internal mammary artery (BIMA) grafting versus single IMA (SIMA) grafting remains uncertain. In this study, we examine the association between Distressed Communities Index scores and the decision to use BIMA grafting. Methods: This multicenter retrospective study includes patients who underwent primary coronary artery bypass grafting with BIMA or SIMA between 2015 and 2024. Patients with 1 distal anastomosis and without an IMA graft were excluded. The Distressed Communities Index is a validated, zip code-based metric that reflects socioeconomic distress using 7 indicators, with higher scores indicating greater distress. It was used to assess the association between socioeconomic factors and both the likelihood of receiving BIMA grafting and postoperative outcomes. Results: Of 17,110 patients, 13,692 patients (80.0%) received SIMA grafting, whereas 3418 patients (20.0%) received BIMA grafting. The median age was different between 2 groups (63.0 years; range, 56.0-70.0 years vs 68.0 years; range, 61.0-74.0 years; Conclusions: Patients from more distressed communities are less likely to receive BIMA grafting. This suggests that surgeons may unknowingly consider socioeconomic factors as part of their decision making for BIMA grafting.
