Diff = Difference between means, adjusted for outcome at baseline; Reference group is Group 1

n = Number of GPs

SD = Standard deviation

95%CI = 95% Confidence Interval. Linear regression was fitted on the mean score for each practice.

Nb. One GP in Group 2 did not have baseline information (excluded from the total)

Group 1 = Asthma Education + guidelines

Group 2 = Guidelines only

Group 3 = Alternative (ear, nose and throat) education only
