查询词典 multivariate analysis

The author concludes that, although the method of "multivariate statistical analysis" has the similar motive and working mechanism with symptom complex diagnosis, they have their own limits in application: sometimes the limit can be conquered when the methods applied combined, but some of the limits can not be conquered, so we should grasp the methods neatly in practice.

但是，由于各种多元统计分析方法自身的特点，在具体的应用中又都存在着各自的局限，有些通过几种方法联合应用可以克服，但有些却是克服不了的，在实际应用中要灵活掌握。

Results 155 patients had surgical site infections in total 1 589 patients undergoing general surgery and the infection rate was 9.75%. The infection rates were hightest in those undergoing celiotomy or colon surgery. 56 patients appeared with postdischarge surgical site infection, accounting for 36.13% in the whole infection public. Most postdischarge surgical site infection happened in class Ⅰ and class Ⅱ surgery. Albumin and hemoglobin abnormity, emergency surgery, bleeding, incision type and eduction were risk factors of surgical site infection by multivariate Logistic regression analysis.

结果 1 589例次手术患者中，155例次手术部位发生感染，感染率为9.75%；不同手术类别相同危险指数的手术以剖腹探查手术和结肠手术感染发生最高；有56例患者在出院后发生手术部位感染，随访感染占总感染例数的36.13%，随访感染以Ⅰ、Ⅱ类手术为主；经单因素及多因素Logistic回归分析得出，白蛋白及血红蛋白值异常、急诊手术、失血、切口类型、引流为手术部位感染的危险因素。

The multivariate logistic stepwise regression analysis showed that compared with individuals with no drinking milk,or no fish and aquatic product intake,or no drinking tea,or no sucrose intakes,the milk intakes 250-1500 g/week(OR=0.731,95%CI:0.542-0.987),the fish and aquatic product intake with 250-1000 g/week(OR=0.720,95%CI: 0.541-0.959),or sucrose intakes 250 g/month(OR=0.446,95%CI:0.255-0.779),drinking tea forepassed(OR=0.635,95%CI:0.458-0.883),and current (OR=2.084,95%CI:1.390-3.125) had different levels of risk on MS.

Logistic逐步回归分析结果提示，牛奶摄入、水产品摄入和饮茶是代谢综合征的保护因素，而年龄和糖摄入是代谢综合征的危险因素，其中牛奶摄入在250～1500 g/周(OR=0.731，95% CI=0.542～0.987)，水产品摄入在250～1000 g/周(OR=0.720，95% CI=0.541～0.959)以及以前饮茶（OR=0.446，95% CI=0.255～0.779和现在正在饮茶(OR=0.635，95% CI=0.458～0.883)，对代谢综合征的保护作用明显，而糖摄入250 g/月时代谢综合征的患病的危险是不食用食糖的2倍(OR=2.084，95% CI=1.390～3.125)。
