†
The frequency (f) of symptomatic hypotension events in the intervention group (f = 18) during study was not significantly different than during the pre-study period (f = 19) (P=0.89). The frequency of events in the control group during study (f = 13) was not significantly different than during the pre-study period (f = 16) (P=0.71).
‡
The change in frequency (Δf) from pre-study to during study was not significantly different between the intervention group (Δf = −1) and the control group (Δf = −3) (P=0.56).
