Student's t-test and χ2 test were conducted to compare the difference between the two populations studied (residents and migrants) and mean, median and proportion were utilized in descriptive analysis of the quantitative data.
Continuous variables were expressed in descriptive terms, stating medians, means, interquartile ranges (IQR) and 95% confidence intervals.
Median values and percentile ranges were used in descriptive analysis for continuous variables.
Continuous patient factors were dichotomized in descriptive tabulations by using the median as a cut-point.
TICS was negatively skewed, so suitable robust statistics for central tendency and spread of skewed variables, such as the median (Mdn), the median absolute deviation (MAD), and absolute range (range = max − min), were used in descriptive statistics.
In descriptive statistics, continuous variables are presented as means ± standard deviation (or medians with interquartile range), and were evaluated statistically using the Student's t-test.
All other parameters will be estimated in a descriptive analysis with report of means, medians, ranges and confidence intervals.
In the descriptive statistics of the data, mean, standard deviation, median, minimum-maximum, ratio, and frequency values were used.
In addition, descriptive statistics for categorical variables were specified as number, and median statistics for numeric variables were reported with range (minimum to maximum) and mean ± SD.
In the descriptive statistics, categorical data were expressed as percentages; continuous data were expressed as median and interquartile range (IQR).
