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)
Selected participants after initial screening with blood pressure will be randomized into two separate groups , using a computer programe for randomization (one group goes with plums juice and other group goes with placebo plum juice). The placebo and plum juice will be packed in unlabeled opaque bottles to maintain double blinding and this juice will be given to participants on their visit.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Once the potential participants were recruited after initial screening, the patient data will be entered in to computer for creating a randomization of participants in to 2 groups.

Efficacy
Statistical methods / analysis
Male and Female participants (n=70) between the ages of 18-65 who are overweight with a BMI of greater than 25 or a waist circumference >94cm (male), >80cm (female), systolic blood pressure 130-159 mmHg and diastolic blood pressure 85-99 mmHg will be recruited for this study. The sample size was determined by statistical power analysis (two tailed t-test at the 5% significance level for the power of 90%) of expected differences in the major measured variable of experiment i.e. systolic blood pressure (Brocel et al 2010). Twenty five participants in each group are required for significant differences in outcome measures. However due to the high dropout rate in human trials the maximum number of participants to be recruited is 35 in each group
