Mean and SD values of post-operative pain (VAS) within each group at days 3, 7, and 14

Group	Postoperative pain (VAS) mean (±SD)			value
	Day 3	Day 7	Day 14
Test (Modified pouch technique)	4.62 (±2.56)^A	2.62 (±1.51)^AB	0.00 (±0.00)^B	0.001
Control (Pouch technique)	4.25 (±3.15)^A	3.25 (±2.71)^AB	0.00 (±0.00)^B	0.005
-value	0.665ns	0.450ns	NA

Means with different superscript letters within the same horizontal row are significantly different. NA: Not Applicable, ; significant () ns; nonsignificant ().
