Statistical Analysis
Data was analyzed using STATA version 16. Data was reviewed for any missing information, illegible responses, and any other inconsistencies before the analysis. Qualitative data were reported as frequencies and percentages. Quantitative data were reported as means with standard deviations and/or medians with inter quartile ranges. After checking normality of qualitative data, we carried out Wilcoxon signed-rank test to analyze the median significant difference of POCUS interpretation time with auscultation time, CO2 detection time, and chest X-ray time. Specificity statistical analysis was carried out between POCUS users and expert interpretation. Kappa statistical analysis was applied to check agreement between the POCUS expert and participant observation. P-values < 0.05 were considered as significant.
