Adherence to airway clearance regimen versus top latent clinical components from PLSR model. Corresponds to a partial least squares regression of adherence to airway clearance only (outcome labelled as AC). Input variables (black text) are abbreviated as in Fig. 1. Inputs contributing unique explanatory value to an outcome are located on outermost circles, suggesting that parent self-efficacy and distance travelled to the CF center for care are the primary predictors of adherence to aerosolized medication
