The same idea applies to hazard ratios. For a hazard ratio of 2, the interpretation is that the probability is double regardless of the timespan. If the underlying hazard rates change during the study, that affects the HR, and we can’t use it to obtain meaningful results. There are meth...
Therefore, no statistically significant difference existed between treatment groups in their hazard rates at the 5% level of significance.The hazard ratio does not estimate the extent to which revaccination shortened length of life compared with controls (c is false), only that revaccination increased...
The HR and RMST-based measures were in agreement regarding the statistical significance of the effect, except in one case. The median HR was 0.84 (Q1 to Q3 range, 0.67 to 0.97) and the median difference in RMST was 1.12 months (range, 0.22 to 2.75 months). The average ratio of the ...
Estimates of hazard ratio from hypothetical survival data were examined, under the condition that the survival is affected by two prognostic factors X1 and X2 with two discrete values (0, 1) which are strongly correlated. Survival curves from the data were assumed to fit an exponential function...
The individual contribution of covariates to the model can be assessed from the significance test given with each coefficient in the main output; this assumes a reasonably large sample size.Deviance is minus twice the log of the likelihood ratio for models fitted by maximum likelihood (Hosmer and...

Therefore, the P value for the hypothesis test of statistical significance for the population hazard ratio would be less than 0.05 (that is, 5%). The null hypothesis would therefore bePhilip SedgwickLouise MarstonHazard Ratios | Bmj
