Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants will be randomly and equally assigned to two groups (saffron and placebo). These groups are named group 1 and group 2, respectively. The research investigators and participants will be unaware of which treatment these groups represent. This computer-generated randomisation structure will comprise 8 randomly permuted blocks, containing 10 participants per block. Participant identification number (1 to 80) will be allocated according to the order of participant enrollment in the study. Allocation is not concealed.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomisation calculator (http://www.randomization.com).

Efficacy
Statistical methods / analysis
Based on previous studies on herbal ingredients for the treatment of menopausal symptoms in women, we are predicting an effect size of 0.6. Based on this, a total sample size of 72 is required. This gives an 80% chance of finding an effect at a statistical significance of 0.05. In this study, we will be recruiting 80 participants, which should give us the suitable power to find an effect, even after dropouts.

Pre and post analyses will be conducted to determine changes in the following:

1. Greene Climacteric Scale (GCS)
2. Quality of life measure: Short form -36 (SF-36)
3. Positive and Negative Affect Schedule (PANAS)

Summary
Brief summary
In this randomised, double-blind, placebo-controlled study, 80 perimenopausal women experiencing climacteric symptoms (e.g., hot flushes, sweating, insomnia, mood changes, muscle pain, joint and back pain, vaginal dryness, urological symptoms, or sexual disorders) will be randomly assigned to receive tablets containing either a saffron extract (affron, 14mg twice daily) or a placebo for 12 weeks. We will assess changes in climacteric symptoms and quality of life through the completion of validated questionnaires.
