BPXR, biplanar X-ray; C3–C7, cervical curvature between the third and seventh cervical vertebrae; Vrelax, lung volume which corresponds to the functional residual capacity during BPXR acquisition; Vmax, lung volume after maximal inspiration during BPXR acquisition; Vmin, lung volume after maximal expiration during BPXR acquisition; r_s, Spearman’s correlation coefficient; p: associated p-value; q: p-value adjusted with Benjamini–Hochberg’s correction for multiple testing.
