Sentence examples for negative hazard from inspiring English sources
In other words, a negative hazard rate indicates increased survival chances with increasing value of the predictor variable (Therneau and Grambsch 2000).
As noted above, the user must take care that this does not lead to a negative hazard, e.g., by using an Emax model with Emax constrained to be not greater than −1.
With a median follow-up of 6 years, 42 additional cases of CIN2+ were identified; women who were HPV positive at baseline were more likely to develop CIN2+ than those who were HPV negative (hazard ratio (HR) 17.2; 95% confidence interval (CI) (9.3 31.6)) and the risk increased with increasing viral load.
The exponential forms of the hazard are useful because they avoid negative hazards as long as λ0 is not negative.
Poor correlations between expert opinion and Risk Assessment may reflect the latter's focus on negative hazards, rather than on both negative and positive welfare aspects, and it may reflect the RA's focus on component hazards rather than on overall (risk for poor) welfare (both as indicated in [ 10]).
The results were similar for arterial carbon dioxide tension (P. aeruginosa culture-positive: hazard ratio 1.134 955% CI 0.758 1.697), p=0.539; P. aeruginosa culture-negative: hazard ratio 1.074 955% CI 0.842 1.369), p=0.572), indicating that it was not associated with survival.
However, proportional Cox hazard analysis, which was conducted separately for each group, indicated that exacerbation rate had no impact on mortality (P. aeruginosa culture-positive: hazard ratio 1.334 955% CI 0.351 5.067), p=0.672; P. aeruginosa culture-negative: hazard ratio 2.161 955% CI 0.576 8.112), p=0.253).
The hazard of death for patients with CA IX-positive tumours was approximately two and half times that for negatives (hazard ratio (HR)= 2.63; 95% confidence interval (CI) 1.21 5.70; log-rank P=0.01).
Both CD56 negative tumors (Hazard ratio: 2.6 (95% CI: 1.14-6.00); p = 0.019) and K-ras mutations (Hazard ratio: 4.74 (95% CI: 1.8-12.3); p = 0.001) contribute as significant independent negative prognostic factors for the PFS (table 3).
Here, negative HR (hazard ratio) means the lower DEG expression the worse the prognosis.
In the subgroup of ART-naive patients, HLA B∗5701-positive individuals were more likely to achieve an undetectable viral load than negative [adjusted hazard ratio (AHR) = 1.60, 95% CI (1.28 2.01) (Table 2)].
