What is the upper bound of the 95 confidence interval?
So for the USA, the lower and upper bounds of the 95% confidence interval are 34.02 and 35.98. So for the GB, the lower and upper bounds of the 95% confidence interval are 33.04 and 36.96.
What do the upper and lower bounds for the 95 confidence interval mean?
An upper one-sided bound defines a point that a certain percentage of the population is less than. Conversely, a lower one-sided bound defines a point that a specified percentage of the population is greater than.

What is the default confidence interval on the survival curve?
The level for a two-sided confidence interval on the survival curve. Default is 0.95. The lower time boundary for the simultaneous confidence limits. If it is missing the smallest event time is used. The upper time boundary for the simultaneous confidence limits. If it is missing the largest event time is used.
How to calculate confidence limits in Survival Object?
A survival object for which the new confidence limits should be computed. This can be built using the “Surv” and the “survfit” function in the R package “survival”. “km.ci” modifies the confidence limits in this object. The level for a two-sided confidence interval on the survival curve.
Which is confidence interval based on the log of the hazard?
One is the “loglog” confidence interval, an interval which is based on the log of the hazard. The other competitive confidence concept was introduced by Rothman (1978) and is using the assumption that the survival estimator follows a binomial distribution.
