OnBetablockers
New in R8. Is the volunteer on betablockers? As indicated by nurse at the time of doing treadmill test. Volunteer's affermative answer is recorded as yes. The data is then reviewed by the PA team and corrected where additional information (eg notes on form) indicates betablocker useage. This is a much more accurate indication of betablocker useage then BNF_Betablocker variable.

Phase 2 data. Activity energy expenditure based on combined acceleration and heart rate using group cal (kJ/kg/day); Pwear based on acceleration only signal. Where possible; a specific group equation is derived for that study using data from the IC tests. Where this is not possible; the most appropriate equation from another study will have been applied in the calculation of the group estimated physical activity energy expenditure results. Present for all those who have a valid free-living file i.e file present; no corruptions deemed to affect combined acc and heart rate estimate and >20hrs Pwear(Measured/Derived from or related to Acitheart Monitor/Data )
