Notes: Means adjusted for age, gender, race/ethnicity, brand, total volume, IPI, velocity 1. Arithmetic mean 2. Geometric mean The table above shows the geometric average values, percent change Pre and Post RIP compliance, B and statistical significance for all biomarker variables. The model is adjusted for age, gender, race, brand, and topography covariates. All significant changes are noted by bold p values. All participants who did not complete the study were excluded for analysis. |
