Table 6.
Comparison of the incidence of the six histopathological BCC subtypes depending on whether the subjects were from an urban or rural environment.
| BCC Subtypes | t | Sig. Two-Tailed | Average of the Incidence of BCC Subtypes * |
|
|---|---|---|---|---|
| Urban (N = 110) | Rural (N = 106) | |||
| Incidence of nodular BCC subtype | 1.01 | 0.314 | 1.87 | 1.92 |
| Incidence of adenoid BCC subtype | 0.14 | 0.891 | 1.20 | 1.21 |
| Incidence of superficial multicentric BCC subtype | 2.01 | 0.048 | 1.22 | 1.12 |
| Incidence of cystic BCC subtype | 1.01 | 0.283 | 1.25 | 1.31 |
| Incidence of infiltrative BCC subtype | 0.28 | 0.777 | 1.15 | 1.13 |
| Incidence of keratotic BCC subtype | 2.15 | 0.033 | 1.06 | 1.01 |
t = value of t; sig. (two-tailed) = 5% significance level of t (confidence interval is 95%). * Incidence averages were obtained by coding each histopathological BCC subtype, with 1 = absent and 2 = present.
