Table 2. Modified Quick Score (Q) method for immunohistochemistry protein expression analysis.

Proportion score (A)	Intensity score (B)
No signal <1% - 0	No signal - 0
Proportion of positive cells 1%-10% - 1	Weak signal - 1
Proportion of positive cells 11%-33% - 2	Moderately strong signal - 2
Proportion of positive cells 34%-66% - 3	Strong signal - 3
Proportion of positive cells 67%-100% - 4

Q = A + B, where Q marks the Quick Score total result; A = proportion score; B = intensity score; minimum Q score was 0 and maximum was 7.
