Interrater Reliability of Ultrasound in the Diagnosis of Sialolithiasis: Methodological Issues

We read the recently published article by Goncalves M et al. with great interest. This paper was published in the February 2019 issue of the European Journal of Ultrasound [1]. The author aimed to assess the interobserver reliability and agreement of offline analyses of three different ultrasound techniques for assessing tubal patency. They assessed interrater reliability by applying Cohen’s kappa coefficient (κ) and percentage agreement in 100 consecutive patients with signs of obstructive sialadenopathy. They reported that overall agreement among the seven observers was substantial (κ = 0.76).
