Multiple logistic regression analysis of factors predicting surgical success (MH closed)

Parameter	Coefficient	95% CI	p	Sign. level
MLD	0.006	0.001678 to 0.01249	0.015	*
BD	0.002	-4.239e-005 to 0.005160	0.068	ns
H	0.001	−0.007413 to 0.008960	0.735	ns
Ar	− 0.569	−8.378 to 3.570	0.835	ns
Cy	< 0.001	−6.339e-005 to 0.0001567	0.407	ns
VA preop	−0.231	−2.465 to 2.030	0.839	ns

In multiple logistic regression analysis, only parameters with highly significant differences (min. p ≤ 0.01) between the MH closed and MH persisting groups were included, and macular hole indices were omitted due to multicollinearity/redundancy of the data. The aperture diameter was the strongest predictive factor for surgical success. Abbreviations: CI confidence interval, MLD minimum linear diameter, BD base diameter, H max. Height, Ar area of MH, Cy area of pseudocysts, VA visual acuity; ns: not significant; *: p ≤ 0.05
