*Adjusted for age, sex, and most recent record of body mass index before the index date.
34 35 36 37 Age and the most recent record of body mass index before the index date were handled as continuous variables in the analyses.
Cases were matched to surgeon, gender, body mass index, age, and date of surgery controls (n = 20) who underwent primary unilateral TKA without developing VTE before patient discharge.
A small number of fields, such as body mass index and expected date of delivery, are automatically calculated from other fields within the computerised template.
