a
Limited sample includes only one manuscript when multiple studies were published using overlapping data
b
One study used both wrists
c
One study used the Low sensitivity and one study used the High sensitivity
d
Two studies used a 15-minute epoch, one study a 15-second or 30-second epoch, and one study a 10-second epoch
