Primary outcomes

1. Body Mass Index (BMI)

   BMI is a measurement of a person's leanness or corpulence based on their height and weight, and is intended to quantify tissue mass. It is widely used as a general indicator of whether a participant has a healthy body weight for their height. Index date for (i) mCSPC participants were defined as date for the first record of mPC (ii) mCRPC participants were defined as date for progression to castration resistant (if =3 months from castration-sensitive treatment initiation \[1st control usually at 3 months\], considered de novo CRPC).
