marginally significantP = 0.049
If area of parapapillary beta zone was added as independent parameter, smaller beta zone was highly significantly ( P <0.001; standardized coefficient beta: −0.12; regression coefficient: −0.81 (95%CI): −1.06, −0.56) associated with a higher RNFL visibility score, while the association between a higher RNFL visibility score and absence of glaucoma became marginally significant ( P = 0.049).
