Spss version 15.0 statistical software package

The results are presented as the mean ± standard deviation (mean ± sd). The drug concentration at the starting time of preparation for FC and NH was identified as 100%, and all subsequent sample concentrations were defined as a percentage of the initial concentration. The drug admixtures were considered chemically unstable if a change of more than 10% occurred within each individual container. The change in drug concentration in the solutions at the different time points was analysed by linear regression analysis. The SPSS version 15.0 statistical software package (SPSS Inc., USA) was used to perform all statistical analyses.

SPSS version 15.0 statistical software package (SPSS Inc., Chicago, USA) was used to carry out statistical analysis. Descriptive statistics of mean, standard deviation, and percentage were used to present the data. Gender differences in verbal and visual perceptions were examined using Chi-square test. Differences between self and people perceptions were examined using McNemar test. Spearman correlation was used to find correlation between body size perception and measured BMI while kappa coefficient (K) was used to calculate degree of agreement. The kappa coefficient is a measure of agreement: K = 1 is a perfect agreement while K = 0 is the weakest agreement. For the kappa coefficient and Chi-square analysis we re-grouped BMI categories into four from five groups used in the questionnaire (we combined obese and morbidly obese group). For McNemar analysis we re-grouped BMI categories into 2 × 2 tables. P < 0.05 was considered to be statistically significant.
