You are at Wits to study medicine and the health sciences. Please check with your lecturers and tutors as to which citation style you should use before submitting any written work, but WHSL strongly suggests you begin to learn the language of communication in medicine, especially if you have enrolled for an MBBCh. Part of this language is using the Vancouver style for medical citations.
Whichever style you finally opt to use, remember that the key to good citation practice is consistency. Choose one style for your written work, and keep the same style throughout that piece of work. Punctuation is extremely important.
You will soon get used to reading and citing references to medical text books and journals.
