Significant difference between groups in mean post-operative pain at donor site. During the first 30 days following maxillary reconstruction with either calvarial (n = 10) or anterior iliac crest (n = 10) bone grafts, participants scored the pain felt at donor site using a 100-mm VAS scale (‘0’ represents ‘no pain’ and ‘100’ represents ‘worst pain ever’). The mean VAS scores for pain ranged from 32.5 ± 17.1 (day 2) to 3.5 ± 15.8 mm (day 14). A linear mixed model determined a significant difference between treatment groups with an estimated effect of 0.09 (standard error = 0.015) for the anterior iliac crest group (G = 31.3, p = 0.00), meaning the pain scores of anterior iliac crest group are higher than the calvarium group scores (F = 31.30, p < 0.00)
