Following publication of the original article [1], the authors identified an error in Fig. 3. The correct version of Fig. 3 is given.
Calibration curves of the 1, 2, and 3-year overall survival and risk stratification. A (a–c) Calibration curves of the 1, 2, and 3-year OS for pregnant women with PH in the Follow-up set. B (a–c) Calibration curves of the 1, 2, and 3-year OS for pregnant women with PH in the Validation set. The light blue line indicates the ideal reference line where predicted probabilities would match the observed survival rates. The red dots are calculated by bootstrapping (resample: 1000) and represent the nomogram’s performance. The closer the solid red line is to the light blue line, the more accurately the model predicts survival. C Kaplan–Meier OS curves for the low-risk and high-risk pregnant women with PH stratified by the prognostic nomogram in the Follow-up set. According to the median cut-off value, samples were divided into high-risk and low-risk groups. D Kaplan–Meier OS curves for the low-risk and high-risk pregnant women with PH stratified by the prognostic nomogram in the Validation set. OS overall survival, PH pulmonary hypertension
