Stars compare each health plan’s rating or composite score to the Utah average. Separate averages were calculated for PPOs and Medicaid health plans. The 95% confidence interval was used to determine statistically significant differences between a health plan’s score and the state average. Three stars indicate that a health plan’s performance on a particular measure is significantly above the state average, while one star means that a health plan’s performance is significantly below the state average. Two stars indicate that a health plan’s performance on a particular measure is not significantly different from the state average. A standardized NCQA data analysis program was used to compute the star ratings.

|Average||HMO/PPO score is neither higher nor lower than the average for Utah HMO/PPOs|
|Lower||HMO/PPO score is significantly below the average for Utah HMO/PPOs|
