TABLE 1.

Mean Hemoglobin-Indices of Test Site Blanching Responses by Treatment Regimen (N=20 subjects)

	PDL + Imiquimod	PDL alone	Imiquimod alone
Pre-PDL^a	29.17 ± 5.93	29.17 ± 5.93	29.17 ± 5.93
1 month	8.42 ± 1.47^*	12.58 ± 2.31	28.12 ± 2.70
3 months	8.78 ± 1.54^*	13.79 ± 2.52	28.38 ± 2.79
6 months	9.46 ± 1.79^*	15.26 ± 2.74	28.67 ± 2.37
12 months	9.96 ± 1.75^*	17.68 ± 2.51	28.85 ± 3.58
Δ12 vs. 1 month	1.54^*	5.10	0.73

All subjects received each of the three treatment regimens: (A) PDL + Imiquimod; (B) PDL alone; and (C) Imiquimod alone.

Pre-PDL values represent the mean hemoglobin-indices for all 20 subjects based on measurement on each lesion before assignment of test sites to one of the three treatment regimens. Every effort was made to place the test sites on optically uniform areas of the PWS.
