RPS12 and pulmonary hypertension: To further investigate the relationships among the SRP-DGs and risk of SSc-PH, we constructed a nomogram model using seven SRP-DGs (RPL32, RPS12, RPS14, RPS23, RPS3, RPS7, and SRP9) to predict the risk of pulmonary hypertension complications in patients with SSc (Figure 9A).
