Statistical methods / analysis
Sample size calculation with alpha and beta set at 0.05 and 0.8 respectively and an effect size of 0.3 requires a minimum of 22 people per arm. We aim to enroll 60 participants (30 women and 30 men) to complete 25 participants in each arm (50 in total).
A multilevel repeated measures analysis will be undertaken over the 84 daily measurements and 2 doses using SPSS. The analysis will look at the total population and then women and men separately.

Summary
Brief summary
The primary objective of this clinical research is to establish the effects of a standardised green-lipped mussel lipid extract (PCSO-524) in women and men with osteoarthritis (OA) of the knee. The study seeks to determine the effective dosage and will be conducted using an open-label design and is categorised as a Phase II clinical trial. Participants meeting the enrolment criteria will be randomised to either 200mg or 400mg daily for a 12 week period. The primary validated measurement will be the Comprehensive Osteoarthritis Test (COAT) which we developed in previous clinical trials on OA. The results will be used to inform a Phase III randomised controlled study.
