S/C ratio: The ratio of the splenic portal vein width to the compression area vein width; CP: Chronic pancreatitis; AP: Acute pancreatitis; PHC: Pancreatic head cancer; PBC: Pancreatic body cancer; PTC: Pancreatic tail cancer; IgG4-P: IgG4 pancreatitis.

Table 2 Spearman correlation analysis of gastroscopic grade and various factors

	Sex	Age	Splenic portal vein width	Compression area vein width	S/C ratio	Varicose vein range	Rib unit
Correlation coefficient	0.757	-0.296	0.330	-0.405	0.518	0.873	0.436
P value	< 0.001	0.091	0.067	0.031	0.007	< 0.001	0.021

P < 0.05 indicates statistical significance. When the correlation coefficient is closer to 1, it means that the correlation of the parameter is stronger. Negative values represent a negative correlation. S/C ratio: The ratio of the splenic portal vein width to the compression area vein width.
