Multivariate analysis for prediction of MD slope deterioration

Factors	Odds ratio (95% CI)	P-value
Baseline refraction (per 1D)	1.13 (1.03–1.25)	0.0108*
IOP reduction rate (per 1%)	0.97 (0.94–0.99)	0.0150*

Notes: Baseline refraction and IOP reduction rate treated as explanatory variables. MD slope deterioration treated as objective variable. Odds ratios were the values with each 1D increase (1D shift toward hyperopia) in baseline refraction or with each 1% increase (1% greater rate) in IOP reduction rate.

^*Statistical significance.

Abbreviations: D, diopter; CI, confidence interval; IOP, intraocular pressure; MD, mean deviation.
