2.4. Statistical Analysis
All statistical tests were processed with STATISTICA 10 software (StatSoft, Paris, France). Means and SD (standard deviation) values were calculated for each variable. When the Shapiro–Wilk test showed that the data were normally distributed, parametric tests were performed. For the effects of Ramadan fasting, data were analyzed using a two-way ANOVA (3 (Phases) × 2 (Time of day)) with repeated measures. For the effect of Caff, data were analyzed using a three-way ANOVA (2 (test periods) × 2 (time of day) × 2 (Caffeine)) with repeated measures. Where appropriate, significant differences between means were tested using Tukey’s HSD Post-hoc test. One-way repeated measures ANOVA (3 test periods) was used to analyze the data: PSQI, body mass, BMI, energy intake, fat (g), carbohydrate (g), and protein (g). When significant differences were reported, the Tukey Post-hoc test was used to test between means. A significant level was considered as
