Patients' mean pain levels assessed using the verbal pain scale and visual analog scale
Postoperative Intraoperative 0 minutes Verbal pain scale % 78.
Unreliability of the visual analog scale
in experimental pain assessment: a sensitivity and evoked potentials study.
It was found that in drain group (Group A) median (IQR) of post operative hospital stay and pain on 1st postoperative day on visual analog scale
were 2 (1-2) and 2 (2-3) respectively and in non drain group (Group B) median (IQR) of postoperative hospital stay and pain on 1st postoperative day on visual analog scale
were 1 (1-1) and 1 (1-1) respectively.

response of patients undergoing cataract surgery under topical anesthesia.
Pain intensity was examined by a Visual Analog Scale
 and function was measured with Neck Disability Index (NDI) both pre-treatment and post-treatment by self- administered questionnaires.
Data Source: Visual analog scale
scores recorded on weekdays and weekend days by 157 patients with osteoarthritis.
Exit site erythema, edema, exudate, and general quality of wound healing were graded during monthly follow-up using a visual analog scale
[worse (0) to better (10), relative to cuffed tunnelled catheter (5)].
The children rated their pain before they received the pain medication (baseline) and then every 30 minutes for 120 minutes using a visual analog scale
(a 100 mm hatched line with "no pain" at one end and "worst pain" at the other).
