Tumor local control rate (LCR) at 7 and 14 days
versus (a) light fluence, (b) PDT dose at 3 mm tumor depth,
(c) [1O2]rx at 3 mm tumor
depth. The solid lines are the sigmoid function (y=100/(1+
exp(b-cx)) for (b) and (c) fits, the resulting goodness of fits are
R2 = 0.20 (0.33), 0.52 (0.68), 0.72
(0.72) for light fluence, PDT dose at 3 mm, and
[1O2]rx at 3 mm for
LCR at 14 (7) days,
respectively.
