Multivariate Cox regression analyses of the prognostic relevance of GRP78 expression in PDAC subgroups in which the poorer overall survival of patients was significantly associated with high GRP78 expression (identified by the log-rank test).
| Subgroups | RR | 95% CI | p value * |
|---|---|---|---|
| Females | 2.222 | 1.031–4.790 | 0.042 |
| G1–2 | 1.808 | 1.136–2.876 | 0.012 |
| Size > 4 cm | 1.668 | 0.824–3.378 | 0.155 |
| Head of pancreas | 1.639 | 0.996–2.697 | 0.052 |
| PNI negative | 2.101 | 1.143–3.863 | 0.017 |
| N1 | 1.763 | 0.955–3.254 | 0.070 |
Note: The boldface type indicates a significant difference. PDAC, pancreatic ductal adenocarcinoma; RR, relative risk; CI, confidence interval; G1, well differentiated; G2, moderately differentiated; PNI, perineural invasion; N, lymph node. *Cox regression test.
