GCG and neurohypophyseal diabetes insipidus: The mixed model comparing both groups shows that first, there is no effect between glucagon compared to placebo on OT (difference: –0.5 pg/ml; 95%–CI [–25, 24]; p = 0.97), and second, that there is no significant treatment-by-group interaction effect, meaning that the effect of glucagon administration was not different in patients with AVP deficiency compared to healthy participants (interaction: 28 pg/ml; 95%–CI [–7, 62]; p = 0.13).
