Sir, The investigation of the probability of an event is one of the basic scientific methods for studying a phenomenon. In medicine, the investigation of the risk of an event may identify its prognosis as well as its aetiology. The article written by Ford et al. is significant, because it is one of the few articles dealing with the risk of breech presentation.

Sekulic et al. studied the recurrence risk of breech presentation in congenital malformations of the uterus.
