1 · What the graph read from it

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.

2 · The registry

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

objectiveThis study was performed to investigate the relationship between the preoperative hemoglobin A1c concentration and late postoperative coronary flow reserve improvement after coronary artery bypass grafting.

methodsThe data of 61 patients who underwent isolated coronary artery bypass grafting were retrospectively analyzed. Coronary flow reserve was measured preoperatively, in the early postoperative period (mean: 2.5 months), and in the late postoperative period (mean: 25 months). The patients were classified into two groups based on their preoperative hemoglobin A1c concentration: Group N (< 7%) and Group D (≥ 7%). Further classification was based on the duration of diabetes mellitus (< 10 years or ≥ 10 years).

resultsThere was no significant difference in early postoperative coronary flow reserve between the two groups. However, in the late postoperative period, Group N exhibited significantly greater coronary flow reserve improvement than Group D (p = 0.012). There was a significant correlation between a lower preoperative hemoglobin A1c concentration and greater late postoperative coronary flow reserve improvement (R

conclusionsThe preoperative hemoglobin A1c concentration predicted coronary flow reserve improvement in the late postoperative period after coronary artery bypass grafting.
