The formula to calculate Cohen’s kappa for two raters is: where: Po= the relative observed agreement among raters. Pe= the hypothetical probability of chance agreement Example Question: The following hypothetical data comes from a medical test where two radiographers rated 50 images for needing fu...

for the potential mediators (Cronbach’s alpha = 0.58–0.84 at baseline and 0.68–0.91 at the intervention’s conclusion) (Table 1). Test-retest reliability, assessed with a separate sample of mothers, indicated acceptable agreement [17] for most items (85% weighted kappa > 0.4 at baseline ...
replicable statistical information on a scale from 1 (low risk of bias) to 4 (high risk of bias) [27]. Inter-rater agreement was calculated using Cohen’s kappa coefficient (k). Using different tools to assess the risk of bias on randomized and non-randomized studies was supported ...
While many individuals may not display symptoms during BV, one of the main reasons contributing to the poor health-seeking behavior of vaginal discharge is shame and fear of judgment by others, which accentuates the need to increase the awareness of BV [10]. The current review aims to ...
