Variables | Means at M1 adjusted for M0 in each hospital | p value* | |
---|---|---|---|
Experimental, n = 302 | Control, n = 311 | ||
*ANCOVA covariance analysis was used for comparisons at M1 between the two hospitals after adjustment for the mean at M0. H0, means at M1 are the same for both groups; H1, means at M1 are different for the two groups. | |||
†ANCOVA could not be used for this variable because of a significant interaction between hospitals and sleeping problems at M0. For this variable, generalised estimating equations28 were used taking into account this interaction: p = 0.2098. | |||
