medians throw out outliers,
otherwise they don't do a lot- hard to factor into
analyses, point quantity, etc. The hazard ratio,
while integrating most of the data is still just
a single number. If the curves being compared don't
fit the model or differ qualitatively it won't
help a lot. Hazard ratio could vary with time,
quoting from the cited work,
"The hazard rate is the probability that if the event in question has not already occurred, it will occur in the next time interval, divided by the length of that interval."
( the time interval goes to zero and you get a point
value for each point )
Most of the time this isn't a big deal
but the "point" is that there is no substitute
for looking at the graph ( similar to watching weather
guy on TV versus looking out the window).
