### Statistical Analysis  
Before considering the average value of all evaluated websites, we performed Fleiss' kappa (k) analysis for both groups to assess the five raters' scores for all websites. The average values of Fleiss Kappa (k) for HPs and LS are 0.3912 and 0.3421, respectively. According to Table 3, the strength of agreement amongst both groups is 'fair.' Kappa (k) values for each website are shown in Table A1 in Appendix A (Column: HPs & LS). As there are five measurements per group, so the calculated values of Kappa (k) show good consistency among the evaluators of each group. Further, to measure the

internal consistency of the DISCERN questionnaire, we calculated [PERSON]'s \(\alpha\) for both evaluating groups. After measuring all questions of DISCERN by each evaluator in HP group, the value of \(\alpha\) is 0.876 which shows higher internal consistency. Similarly, the value of \(\alpha\) for LS is 0.783 which also reflects a good range for consistency of LS group. Both values of \(\alpha\) show that the tool is reliable for evaluation.  
Similarly, Wilcoxon-rank sum test has been used to compute the value of \(p\) at significance level (\(p<0.05\)) for each website evaluated by both groups. The values are shown in last column in the table given on Table 10. Furthermore, the Chi-squared test has been calculated for the DISCERN indicator regarding clarity of sources (Question 4 of DISCERN questionnaire given in Table 10). For HPs, the value of Chi-squared is 0.199148 whereas for LS, it is 0.014612 for statistical significance level (\(p<0.05\)). Similarly, the same Chi-squared test has been carried out for additional source of information (Question 7 of DISCERN questionnaire given in Table 10). So, the value of Chi-Square is 0.024406 for HPs while for LS it is 0.005135 at \(p<0.05\).  
Normality and homoscedasticity tests were performed to check whether the scores are normally distributed for both groups of evaluators. After performing these tests, it is found from [PERSON]'s test (\(p>0.05\)) [45; 46], visual inspection of their histograms and box plots that all the websites scores were normally distributed for both groups. For HPs, the value of skewness is \(-0.078\) (Standard Error (SE) = 0.464) and a kurtosis is \(-1.448\) (SE = 0.902). Whereas for LS, the value of skewness is 0.197 (SE = 0.481) and a kurtosis is \(-0.943\) (SE = 0.935) [47]. Similarly, after examining the Q-Q plots of both groups, it has been observed that all the dots were along the line which indicates that the data are approximately normally distributed. Further, the analysis of both groups showed that they are homoscedastic because they have the same level of variance.  
After confirming normality and homoscedasticity, subsequently, we performed independent samples t-test to find out t-values for the statistical differences of DISCERN questionnaire assessed by both groups. The Independent Samples t-test is a parametric test that compares the means of two independent groups in order to find out statistical evidence for the significant difference between means of the associated populations. It is found that the t-value is 0.09854 and \(p\)-value is 0.921914. The result shows that it is not significant at \(p<0.05\). Lastly, we calculated t-values for the statistical differences of DISCERN questionnaire assessed for all categories of websites. The results are shown in Table 6. It is clear from the results the value of \(p\) is significant at \(p<0.05\) for only Information category websites.
