Sensitivity and specificity of STIC detection for the diagnosis of fetal CHDs.
(A) Pooled sensitivity. (B) Pooled specificity. Effect sizes were pooled by random-effects models. The point estimates from each study are shown as solid squares. The pooled estimates are shown as a solid diamond. Error bars represent 95% CIs. STIC, spatiotemporal image correlation; CI, confidence interval; df, degrees of freedom.

Overall diagnostic odds ratio and summary receiver operating characteristic curves for all data sets describing the diagnostic performance of STIC detection in identifying fetal CHDs.
(A) Overall diagnostic odds ratio. (B) The summary receiver operating characteristic curves for all data sets. Effect sizes were pooled by random-effects models. The pooled diagnostic odds ratio is shown as a solid diamond. Each square in the summary receiver operating characteristic curve represents one study. Sample size is indicated by the size of the square. STIC, spatiotemporal image correlation; CI, confidence interval; df, degrees of freedom; DOR, diagnostic odds ratio; AUC, area under curve.

Sensitivity and specificity of 4
CV+OTV+3 VTV detection for the diagnosis of fetal CHDs. (A) Pooled sensitivity. (B) Pooled specificity. Effect sizes were pooled by random-effects models. The point estimates from each study are shown as solid squares. The pooled estimates are shown as a solid diamond. Error bars represent 95% CIs. 4 CV, 4 chamber view; OTV, outflow tract view; VTV, three-vessel trachea view; CI, confidence interval; df, degrees of freedom.
