Risk of bleeding in patients with continued dual antiplatelet therapy during orthopedic surgery.
Article in Chinese medical journal, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundTo prevent risk of life-threatening stent thrombosis, all patients need to undergo dual antiplatelet therapy (DAPT) for at least 6 weeks to 12 months after stent implantation. If DAPT is continued during noncardiac surgery, there is a risk of severe bleeding at the surgical site. Our study was to assess the risk of bleeding in patients with continued DAPT during orthopedic surgery.
methodsThe clinical data of 78 patients with coronary heart disease who underwent orthopedic surgery from February 2006 to July 2018 were retrospectively analyzed. Prior to orthopedic surgery, DAPT was continued in 16 patients (group I), 24 patients were treated with single antiplatelet therapy (group II), and 26 patients received low-molecular-weight heparin therapy for more than 5 days after the discontinuation of all antiplatelet therapies (group III). Twelve patients were excluded, as they had undergone minimally invasive surgery such as transforaminal endoscopy and vertebroplasty. The perioperative blood loss of each patient was calculated using Nadler's formula and Gross' formula. The intraoperative bleeding volume, total volume of intraoperative bleeding in addition to postoperative drainage, and total blood loss were compared between groups. The level of significance was set at P < 0.05.
resultsThere were no significant differences between the three groups in age, intraoperative bleeding volume, total volume of intraoperative bleeding in addition to postoperative drainage, and total perioperative blood loss calculated by Nadler's formula and Gross' formula (all P > 0.05). Six patients experienced postoperative cardiovascular complications due to the delayed restart of antiplatelet therapy; one of these patients in group III died from myocardial infarction.
conclusionsContinued DAPT or single antiplatelet treatment during orthopedic surgery does not increase the total intraoperative and perioperative bleeding compared with switching from antiplatelet therapy to low-molecular-weight heparin. However, the discontinuation of antiplatelet therapy increases the risk of serious cardiac complications.
