Development of the novel model
As the forest plot shown in Figure 1, two risk factors (i.e., LSM and PLT, sTable 2) of CSPH were identified in the systematic review and meta-analysis, with the pooled OR of 1.10 (95% CI 1.06-1.15) and 0.99 (95% CI 0.98-0.99), respectively. Furthermore, the β-coefficient of LSM and PLT were 0.095310 and 0.01005, respectively. Finally, a novel non-invasive CSPH risk model was developed as follows: 0.095310 × LSM (kPa) - 0.01005 × PLT (×109/L) - 0.11.
