Clinical phenotypes of PDT patients by CFH genotype

Characteristics	CC	TC	TT	P-value
Total number of patients (%)	20 (29.0)	34 (49.3)	15 (21.7)
Mean age (years) (SD)	77.8 (7.2)	78.2 (8.0)	82.1 (9.1)	0.23
% women	60.0	64.7	66.7	0.92
Eyes with predominantly classic lesions (%)	15 (75.0)	14 (41.2)	3 (20.0)	0.003
GLD of lesions (µm) (SD)	3023 (1468)	3061 (1218)	3326 (932)	0.74
Median treatments/month (range)	0.12 (0.02–0.67)	0.17 (0.03–0.67)	0.19 (0.03–0.30)	0.79

CFH, complement factor H; GLD, greatest linear dimension; PDT, photodynamic therapy; SD, standard deviation; VA, visual acuity.

The P-value is from a one-way analysis of variance that compares means of the variables between genotypes using a Bonferroni multiple comparison correction.
