2.8.4. Statistical Analysis
Quantitative variables with Gaussian distribution had their central tendency expressed as the mean and their dispersion quantified by the standard deviation. For variables with non-normal distribution, the central tendency was described by the median and its dispersion by the 25% and 75% quartiles. The Shapiro–Wilk test was used to assess normality. Categorical variables were presented using absolute frequency and percentage.Statistical analyzes for normal quantitative variables, before and after the intervention, were performed using the paired Patients were compared with each other based on capillary blood glucose results obtained during the first and third weeks.The epidemiological, clinical and laboratory data of the patients were compared between groups 1 and 2 in order to assess whether the randomization process generated similar groups from a statistical point of view.The significance level used was 0.05, with SPSS version 20.0 being the software of choice.
