摘 要 目的 系统性评价体质量对新型口服抗凝药(NOACs)、阿司匹林用于全髋关节置换术、全膝关节置换术(以下统称“髋膝
关节置换术”)后预防静脉血栓栓塞(VTE)的有效性和安全性的影响,为合理用药提供循证参考。方法 计算机检索 PubMed、

and knee arthroplasty: a meta-analysis

ABSTRACT OBJECTIVE To systematically review the effects of body weight on the efficacy and safety of novel oral
anticoagulants (NOACs) or aspirin for the prevention of venous thromboembolism (VTE) after total hip arthroplasty and total knee
arthroplasty (hereinafter referred to as “hip and knee arthroplasty”). METHODS Retrieved from PubMed, Embase and Cochrane
library, randomized controlled trial (RCT) and non-RCT about the effectiveness and/or safety of NOACs, aspirin and low-
molecular heparin by subgrouping according to body weight or body weight index [BMI 18.5-<25 kg/m as normal body mass,
2
BMI 25-30 kg/m as overweight, and BMI>30 kg/m as obesity (of them, BMI>40 kg/m as morbid obesity)] were collected

from the inception to June 30, 2022. After literature screening and data extraction, the quality of RCT was evaluated with bias risk
assessment tool RoB 2.0 recommended by Cochrane system evaluator manual. The Newcastle-Ottawa scale was used to evaluate the
quality of non-RCT. Meta-analysis was performed by using RevMan 5.4 software. RESULTS A total of 6 literatures, containing 3
series of RCT pooled studies and 3 non-RCTs were included. The results of meta-analysis showed that among different BMI
subgroups, there was no statistical significance in reducing major VTE and VTE-related mortality of patients with normal body
mass patients [OR=0.63, 95%CI(0.26,1.51),P=0.30], overweight patients [OR=0.48,95%CI(0.22,1.04),P=0.06] and obese
patients [OR=0.70,95%CI(0.40,1.25),P=0.23] by NOACs, compared with enoxaparin. The safety of NOACs was comparable to
that of enoxaparin in different BMI subgroups in terms of the incidence of major bleeding events and major+clinically relevant non-
major bleeding events (P>0.05). There was no statistical
