Limitations and strengths
Despite having employed strategies to reduce interpretational variations, including image classification based on quality, randomized assessment of radiographs, reviews by different professionals, and contrasting readings with radiologists of differing years of experience; we acknowledge certain limitations.
The study highlights a moderate to low interobserver agreement, possibly attributed to the lack of standardized definitions for radiological findings of pneumonia and inherent limitations in chest radiography specificity. It is noteworthy that certain x-ray images were excluded from the study due to variations in the quality and accessibility of chest radiographs across different hospitals.
