Statistical methods / analysis
Data analysis will use descriptive statistics to examine the demographic and baseline characteristics. The primary VAS measure and secondary measures for active and placebo groups will be compared from baseline to week 12 using analysis of covariates (ANCOVA). The linear mixed model will be used to compare baseline scores of primary and secondary measures with those over the course of the 12 weeks of treatment for both active and placebo groups. All data will be presented as mean (SD). Statistical significance will be set at p<0.05. Both an intention-to-treat analysis and a per-protocol analysis will be conducted, the intention-to-treat analysis being of primary interest as it reflects better the effectiveness of the investigational product.

Summary
Brief summary
This study is a 12-week, randomised, double-blind, placebo controlled, clinical trial to assess the effectiveness and safety of a novel herbal formulation, consisting of Curcuma longa (Turmeric), Boswellia serrata (Indian Frankincense) and Zingiber officinale (Ginger) for the management of osteoarthritis of the knee. The study will assess if taking this formulation helps reduce knee pain and improves function and wellbeing from osteoarthritis of the knee. It is expected that the herbal formulation will reduce pain from osteoarthritis of the knee over the course of 12 weeks compared to placebo medication.
