Furthermore, Cox analysis revealed that NQO1 expression emerged as a significant independent hazard factor for DFS rate in patients with cervical SCC.
Moreover, along with clinical stage and lymph node metastasis, multivariate survival analysis demonstrated that NQO1 expression emerged as a significant independent hazard factor for DFS but not for 5-year OS in patients with cervical SCC.
Lead has been identified as a hazard and a risk factor for hypertension development and other cardiovascular diseases [39].
A number of research studies indicated that home hazards were a risk factor for home injuries among young children [ 9- 15].
Cox regression analysis showed the HME as a risk factor for VAP (hazard rate, 16.2; 95% confidence interval, 4.54 58.04; P < 0.001).
The multivariate Cox regression analysis showed the HME as a risk factor for VAP (hazard rate, 16.2; 95% confidence interval, 4.54 58.04; P < 0.001), for VAP caused by Gram-positive cocci, for VAP caused by Gram-negative bacilli, for primary endogenous VAP and for secondary endogenous VAP (Table 2).
In addition, as natural disasters disproportionally affect poorer communities (e.g. Basher [2006]), the contribution of persistent degassing to poverty, poor health and degradation of the local environment makes it a risk factor for acute hazards by increasing vulnerability in the area.
7 In the Cox proportional hazards model, PPV23 was not a risk factor for the events.
Increasing MR was a risk factor for death [hazard ratio (HR), 1.44; P<0.001] and death/heart failure hospitalization (HR, 1.34; P<0.01.34
The use of a fever control protocol was an independent risk factor for VAP (hazard ratio 2.73, 95% confidence interval (1.38, 5.38; P = 0.005)).
