The longer median length of stay in the intervention group meant that smokers in this group had to remain abstinent for longer that patients in the usual care group, although a median difference of one day seems unlikely to account for a doubling in smoking cessation.
Related post-hoc calculations showed limited power to detect differences in individual outcomes of reported PA (23% power to detect a difference of 60 minutes per day, 1.5 days per week) and FV consumption (20% power to detect a difference of one serving per day).
Although we find a statistically significant difference in the number of cigarettes smoked per day, there is no documented evidence that a difference of one half of a cigarette a day will make a significant difference in health outcomes.

In this case of one day, the maximum difference between (v_{hbox{max} } (t)) and (v_{hbox{min} } (t)) is 10.02 m/s, the minimum difference between them is 4.05 m/s, and the standard deviation of the difference between them is 1.38 m/s.
But this new technology could make a difference one day when an emergency call can be made on a phone that's out of power.
