Outcomes
Primary outcome [1] 1120 0

Key exclusion criteria
Any history of, or ongoing, mental or physical condition (including suspected or known diagnosis of ischaemic heart disease), which, in the opinion of the investigator, would impede the subjects ability to participate in the trial.- History of type I or type II diabetes mellitus or previous treatment with antidiabetic medication. - Prior use of testosterone, oestrogen, growth hormone or other oral glucocorticoid or anabolic steroid products within the previous six months. - Alcohol or substance abuse which in the opinion of the investigator would affect the subjects ability to participate in the trial. - Prior use of anti-retroviral agents (including protease inhibitors, nucleoside or non-nucleoside reverse transcriptase inhibitors, investigational antiretroviral agents or fusion inhibitors either in a previous study, as treatment or as part of post-exposure prophylaxis).- Prior use of any retinoid-containing compound within the previous six months. - Abnormal coagulation. - Previous allergic reaction or known allergy to local anaesthetic. - Previous use of psychotropic medications. - Concomitant use of medications, including those metabolised by CYP3A4 enzyme system (appendix C), which, in the opinion of the investigator, would affect the subjects ability to participate in all activities involved in the trial. - Any grade-three laboratory abnormality recorded from screening bloods. - Any grade-two laboratory abnormality recorded from screening bloods, which, in the opinion of the investigator, would impede the subjects ability to safely complete all study requirements. - Gastrointestinal disorders, which may affect drug absorption. - Any finding on screening clinical examination, which, in the opinion of the investigator, would impede the subjects ability to participate in the rest of the trial.- Pregnancy - Evidence of acute or chronic active hepatitis B virus infection by serology performed at baseline. - Evidence of hepatitis C infection by serology performed at baseline.

Purpose of the study
Diagnosis
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Randomisation sequence was generated centrally and kept at a central location in sealed envelopes grouped according to age of potential study participants.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Sequences were generated centrally to ensure a 2:2:1 randomisation stratified to age group to ensure equal recruitment to each arm across a range of ages. Computer generated randomisation cards, specifying a treatment allocation, were then grouped according to age (age groups a-d) and each individual card placed in an envelope marked with the age group. Envelopes remain at a central location and study staff request a treatment allocation based on potential study subjectâ¿¿s age from administrative staff not directly associated with the study.
