<qa>  What is the P-value of less than 0.05?Randomization Randomization will be implemented using Research Randomizer Urbaniak, G. C., Plous, S. 2011. Research Randomizer Version 3.0 Computer software Data for randomization was retrieved on September 25th, 2011, from Three treatments will be randomized for 50 reps totaling 150 patients Analysis of the samples Statistical analysis will be performed by Patrick Haentjens Uz Brussel, Laarbeeklaan 101 1090 Jette; tel 024777909 Statistical analysis Data will be presented as number of cases including nominator and denominator values and percentages for categorical variables and as mean values and standard deviation SD for continuous variables. Differences between treatment arms will be presented as absolute between-group differences with corresponding 95 confidence intervals 95 CI. Differences between treatment arms will be assessed by one-way ANOVA for continuous variables and the test for trend in proportions for categorical variables. All tests will be two-sided, and a P-value of less than 0.05 will be considered to indicate statistical significance.
