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

objectiveWe sought to assess the efficacy of preoperative autologous blood donation in reducing patient exposure to allogeneic blood products following elective cardiac surgery.

methodsWe included 48 patients in a prospective study and randomly assigned them into the control or treatment group. We excluded patients with aortic stenosis, main trunk stenosis and unstable angina. Group A (n=23; coronary disease n=21 and valvular disease n=2) was the control group, and group B (n=25; coronary disease n=21, valvular disease n=4) received preoperative autologous blood donation. All patients had cardiopulmonary bypass surgery, and we processed mediastinal blood with a cell-saver device before reinfusion. All patients received aprotinin, and we reinfused blood shed from the mediastinum postoperatively.

resultsNo major peri- or postoperative complications occurred. We interrupted preoperative blood donation in 2 patients (8%) because of worsened angina pectoris. The mean time between the first blood donation and surgery was 22.5 (standard deviation [SD] 9.4, range 12-50) days. In group A, 9 patients (39.1%) were exposed to allogeneic blood products. In group B, 11 patients (47.8%) were exposed to blood products (p=0.73), and 4 (16%) were exposed to allogeneic blood products (p=0.036).

conclusionPreoperative blood donation was completed in 92% of the targeted low-risk population. The procedure significantly reduced exposure to perioperative allogeneic blood products.
