there was a greater number of adverse events related to the lower extremities in the intervention group than in the control group (100 in the intervention group and 54 in the control group)

This kind of confused me. Seems to imply the intervention group experienced a greater number of "adverse events"?

Adverse events related to the lower extremities includes any reported event -- like blisters, sore feet, twisted ankles -- and other things that you would expect to see increase in a group of people who were encouraged to walk versus a sedentary group.

I interpreted this to mean that the walking group suffered a greater number of leg and foot problems than did the non-walking group.

same overall probability of adverse events in both groups, but the nature of adverse events reported differed between the two.
