In the school-based phase, healthy children were randomly selected from six schools.

The agreements between the standard and the pocket-sized echocardiography were good or excellent for major CHDs in both cohorts (\u03ba statistics &gt; 0.61). Among valvular pathologies, agreements for tricuspid and pulmonary valves\u2019 regurgitation were moderate among school-based cohorts (0.56 [95% confidence interval 0.12\u20131] and 0.6 [95% confidence interval 0.28\u20130.91], respectively). The agreements for tricuspid and pulmonary valves\u2019 regurgitation were excellent (&gt;0.9) among hospital-based population. Other values for valvular findings were good or excellent. The overall sensitivity and specificity were 87.5% (95% confidence interval 47.3\u201399.7) and 93.8% (95% confidence interval 85\u201398.3) among the hospital-based individuals, respectively, and those were 88% (95% confidence interval 77.8\u201394.7) and 68.4% (95% confidence interval 56.7\u201378.6) among the school-based individuals, respectively. The cost of examination was reduced by approximately 70% for an individual using the pocket-sized device.<\/jats:p><\/jats:sec><jats:sec id=\"S1047951119003111_as4\"
