Prevalence of pectus excavatum in an adult population-based cohort estimated from radiographic indices of chest wall shape
Fig 2
Comparison of haller and correction index measurements for men and women from the Dallas Heart Study (DHS) and pectus cohorts.
Haller (A) and Correction (B) indices of the DHS1 cohort (n = 2687) and pectus cases (n = 297) at T6, T8 and superior xiphoid axial levels. Individuals from DHS1 (gray circles) and subjects with pectus excavatum (PE, n = 274, blue circles) pectus carinatum (PC, n = 19, red triangles) or a mixed pectus excavatum and carinatum defect (Mixed, n = 4, orange diamonds) are individually plotted with superimposed box and whisker plots (black). *, ** and *** indicative of P-value <0.05, <0.001 and <0.0001, respectively.
