**Figure 7:** Relationship between DNA-Index of D-type tumors and
percentages of T-, and A-type tumors. Linear regression analysis was used
to assess the relation between D-type tumors and T- (a) or A-type (b) tumors
within an SSI interval 4<SSI≤15 relative units. A strong significant negative
correlation appeared between decreasing D-type DI values of hyperdiploid
tumors (1.020< DI≤1.044) and increasing percentages of T-type tumors (r =
−0.68, p <0.0001; n = 37). A similar but positive correlation appeared regarding
the percentage of A-type tumors (r = 0.84, p < 0.0001; n = 37). |
