Distal Acupoints Outperform Proximal Acupoints in Treating Knee Osteoarthritis: A Randomized Controlled Trial

Table 5

VAS differences between the three groups, post-VAS comparisons, and post hoc analysis.

	PG	DG	SG	value (PG vs DG vs SG)	Post hoc tests
Post-VAS	2.00 ± 1.63	1.40 ± 1.67	2.97 ± 2.06	0.001	SG > DG
VAS difference	−1.74 ± 1.12	−2.27 ± 1.55	−0.84 ± 1.13	0.001	PG > SG; DG > SG

Values are presented as mean ± SD. PG = proximal acupoints group; DG = distal acupoints group; SG = sham acupoints group.
