(N ¼ 24 per group) following
informed consent. After attrition, the sample size was 37 (N ¼ 23 in
the massage group and N ¼ 14 in the waitlist control group) (See
Fig. 1). The greater attrition in the control group, although selfreported
as “scheduling difficulties” could have also related to
remission in neck pain over the waitlist period. This lesser power
would be expected to attenuate the predicted treatment effects.
The majority of the participants were female (77%), averaged 47
years of age, were middle income and were distributed 53% Hispanic,
20% Caucasian, 12% African-American, 9% Asian and 6% other.
The two groups did not differ on these variables.
