STUDIES ON THE QUANTITATIVE EVALUATION OF THE FUNCTION OF STOMACH AND DUODENUM
2. STATISTICAL STUDIES ON CORRELATIONS BETWEEN MEASUREMENT ITEMS OF X-RAY FIGURES

As previously reported, the following 8 items were measured on gastric x-ray images: 1) width at the section of gastric angle (Ba) and gastric body (Bc), and Ba/Bc ratio ; 2) length of antral border at the lesser curvature (L) and the greater curvature (G), and G/L ratio ; 3) middle zone thickness (MZ) ; 4) sawtoothed wave depth (Zhnlg) ; 5) antral peristalsis (AP) ; 6) antral spasm (AS) ; 7) length of duodenal loop (L of D) and 8) number of duodenal longitudinal folds (Lf). Using correlation coefficient and scatter diagram or correlation table in analyzing correlations between four sets of 2 items covering 5 groups, namely Ba/Bc and G/L, MZ and G/L, G/L and AP, and MZ and Zhnlg, and obtained the following results: 1) correlation between Ba/Bc disappeared in the open stage of gastric ulcer ; 2) correlation between MZ and G/L disappeared in the open stage of either gastric ulcer or duodenal ulcer ; 3) correlation between G/L and AP was negative in any one of the groups and 4) correlation between MZ and Zhnlg showed a higher level in the open stage of duodenal ulcer. The above findings presumably indicate characteristic correlations depending on the group.
