Table 2 Mean numeric rating scale (NRS) changes according to the location of major stenosis

From: Therapeutic effect of intraductal saline irrigation in chronic obstructive sialadenitis

Location of stenosis∆ NRS (mean ± sd)
Orifice (n = 2)2.25 ± 2.75
Distal Duct (n = 5)3.60 ± 2.27
Middle Duct (n = 6)4.83 ± 1.84
Proximal Duct (n = 6)2.25 ± 1.15
  1. ∆ NRS = Last NRS–Initial NRS
  2. Kruskal-Wallis test was performed. P = 0.203
