Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
raloxifene at a daily oral intake dose of 120 mg/day. A thirteen week double-blind, cross-over design will be used in which patients will receive either raloxifene or placebo as an adjunctive treatment to their previously stabilized antipsychotic medication. Following treatment in the first 6-week phase, patients will then enter a one week wash-out before entering the second 6-week phase consisting of the alternate treatment (raloxifene or placebo). Thus, in total, participants will be treated with raloxifene for a period of 6 weeks.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants were enrolled and allocated a participant number obtained from Prince of Wales Hospital Pharmacy which controlled the randomization schedule.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation by using a randomization table created by a computer software (i.e., computerised sequence generation).
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
The people receiving the treatment/s
The people administering the treatment/s
The people assessing the outcomes
The people analysing the results/data
Intervention assignment
Crossover

Type of endpoint/s
Efficacy
Statistical methods / analysis
ANOVA, t-tests, cluster analyses. The number of participants was determined on the basis of a power analysis. The number of participants would be large enough to detect an effect of treatment alone, however, the larger sample size was required to detect an effect of treatment on the basis of ESR1 genotype and diagnosis which would reduce the numbers in each of the groups.
