OR = odds ratio.
↵a Adjusted for the potential confounders of sex and age of the patient; the speciality of the doctor submitting the specimen to the pathology laboratory (GP, GP frequent exciser, plastic surgeon, dermatologist, general surgeon, other secondary care specialist); the accuracy of any stated diagnosis; and the biopsy site (head and neck, body, upper limb, lower limb, groin and perineum).
