Predictors of rating scale utility values from diabetic retinopathy patients and ophthalmologists, determined by multiple linear regression.

RS, rating scale; CI, confidence interval; BCVA, best-corrected visual acuity; DR, diabetic retinopathy.
*Backward linear regression with p = 0.1 cut-off for exclusion was used.
Predictors of rating scale utility values from diabetic retinopathy patients and ophthalmologists, determined by multiple linear regression.

RS即评分量表（rating scale）；CI即置信区间（confidence interval）；BCVA即最佳矫正视力（best-corrected visual acuity）；DR即糖尿病视网膜病变（diabetic retinopathy）。
*采用排除界值为p=0.1的反向线性回归分析。
本研究通过多重线性回归分析，明确了糖尿病视网膜病变患者及眼科医师的评分量表效用值的预测因子。
