Anaesthetic injection versus ischemic compression for the pain relief of abdominal wall trigger points in women with chronic pelvic pain

Table 3 Evaluation of percentage of pain relief between groups and intra group (between different times of follow-up)

Groups	VAS Baseline % [median(range)]	VAS 1st week % [median(range)]	VAS 4th week % [median(range)]	VAS 12th week % [median(range)]	P^d
Group 1	0.0 [54 (49–90)]	−45.3^a [30.5 (8–58)]	−60.2^b [10 (0–49)]	−69.9^c [8 (0–39)]	.03
Group 2	0.0 [67 (56–75)]	−18.7^a [50 (47–54)]	−9.2^b [60 (42–61)]	−8.5^c [56 (42–67)]	.47
P	.50	.08	<.01	<.01	---

Notes: all measurements are represented by percentage of pain relief (%VAS) and by median and 25–75 % quartiles (range) of VAS. The minus signal (−) signify reduction of pain scores. Post test for threshold at Group 1: ^a vs ^b = .06; ^a vs ^c = .01; ^b vs ^c = .10; ^d time effect
