Table 5.

Results from method comparison. Entries are difference in means (95% CI) P value. The values are: The mean difference between HADS-d in group N and NN, group 1 and 0; The mean difference between HADS-a in group N and group NN, group 1 and group 0; The mean difference between HADS-t in group N and NN, group 1 and 0.

Difference in means presented for each method. The endpoint mean for the N group is subtracted from the endpoint mean in the NN group. For the modified Ohnmeiss method, the endpoint mean for the group 0 (no markings) was subtracted from the endpoint mean in group 1 (with markings). Hence positive values correspond to larger values on HADS for the NN group or (for Ohnmeiss) for group 1.
