Although the proportion of male patients was higher in the perioperative group, the difference in sex distribution did not reach statistical significance ( p = 0.054).

showed a trendp = 0.078
In subgroup analyses, neoadjuvant CRT showed a trend toward improved OS in EGJ stage II ( p = 0.078) and a significant RFS benefit in distal stage II ( p = 0.014), whereas perioperative ChT demonstrated a significant OS advantage in EGJ stage III ( p = 0.020).
borderline significantp < 0.10
The log-rank p-value was 0.078, suggesting a borderline significant difference ( p < 0.10).
Although the log-rank p-value was 0.164 and therefore not statistically significant, a numerical trend favoring neoadjuvant CRT was observed.
Indeed, the presence of broad confidence intervals and borderline significance levels in some categories suggests limited statistical power.
