Table 4 Comparison of the slope angle and the Haller index in seven patients before and after the revision Nuss surgery

From: A retrospective study on the impact of bar flipping on the recurrence of pectus excavatum after the Nuss procedure

  Before revision surgery After revision surgery p value
Slope angle α (IQR), degrees 39.6 (38.5–52) 10.4 (9.1–23.7) 0.018
cxrHI (IQR) 3.5 (3.1–3.8) 2.9 (2.5–3.1) 0.043
  1. There was a significant difference (p < 0.05) in the α and HI before and after the revision Nuss procedure
  2. p < 0.05 are given in bold
