MKI67 and neoplasm: Several characteristics were less frequent in the radiogenic BRAFV600E-negative PTCs: tumor encapsulation (OR = 0.315, p = 2.15 × 10−4), dominant papillary growth pattern (OR = 0.416, p = 0.002), oncocytic changes (OR = 0.298, p = 4.00 × 10−5), pT2 category (0.385, p = 6.49 × 10−4), zero invasiveness score (OR = 0.549, p = 0.046); the tumors also had an overall lower Ki67 LI (b = −1.714, p = 8.00 × 10−6), in particular 5–10% LI (OR = 0.488, p = 0.022).
