Multiple Regression
To examine whether healthcare utilization is a predictor of HRQOL in youth with SCD, multiple regression analysis was deployed. There was a statistically significant relationship observed between HRQOL and the frequency of ER visits (B = -1.05, P = .04) and hospitalizations (B = -2.73, P = .003) over the past 12 months (Table IV). There was also a relationship observed between age and HRQOL in both regression models (P = .03).
