Statistical analysis of serum @entity7597 ( @entity7597 ) and II ( @entity7598 ) levels, @entity7597 / XXXX ratios and serum @entity8243 levels in a general population.

@entity1 @entity7598 @entity8243 @entity356 @entity7597
To allow adoption of serum pepsinogen as a screening indicator of @entity356 , serum @entity7597 _ II levels, the ratios of @entity7597 / @entity7598 and the serum @entity8243 levels in a general population were studied using 850 samples selected at random from a rural area in Japan. The collected data were analyzed statistically to determine the distribution characteristics by various categories of sex and age. The following results were obtained:1. The distributions of @entity7597 , the ratios of @entity7597 / @entity7598 and serum @entity8243 values largely deviated from the normal distribution. Therefore, the use of non-parametrical methods was recommended for analysis of these data.2. Although no significant difference between all selected @entity1 and all selected @entity1 was observed in any of the three parameters of @entity7597 and @entity7598 levels and the ratios of @entity7597 / @entity7598 , a significant difference between @entity1 and @entity1 was observed for @entity7597 levels in under-fifty age groups. On the other hand, the median serum @entity8243 value (92.0 pg/ml) in all selected @entity1 was significantly lower than that (101.0 pg/ml) in all selected @entity1 . A statistically significant difference between @entity1 and @entity1 was observed in serum @entity8243 levels both in the under-forty age group and in the sixty and over age group.3. No significant difference was observed in the pattern of changes in @entity7597 levels with increasing age in either @entity1 or @entity1 . While @entity7598 levels in @entity1 varied irregularly with advancing age, @entity7598 levels in @entity1 showed obvious increases with advancing age. The ratios of @entity7597 / @entity7598 showed a tendency to decrease with advancing age in both @entity1 and women. Conversely, serum @entity8243 levels increased with advancing age in both @entity1 and @entity1 .
