Comparing acid steatocrit and faecal elastase estimations for use in M-ANNHEIM staging for pancreatitis

Table 2 Stool fat in grams/day by acid steatocrit in M-ANNHEIM stages of pancreatitis

M-ANNHEIM stage (n %)	Median (IQ range) of stool fat in g/d
0, 13 (6.7)	6.3 (6.0-6.6)
I, 87 (44.8)	6.3 (5.9-6.4)
II, 89 (45.8)	7.5 (6.4-10.8)
III, 5 (2.5)	15.3 (12.0-15.6)

A statistically significant difference was present between the different M-ANNHEIM stages (P < 0.001, Kruskal-Wallis test). Comparison between any two stages showed a statistically significant difference between stages 0 and II, and stages II and III (P = 0.002, Mann-Whitney U test) and also between stages 0 and III, I and II, I and III (P < 0.001; Mann-Whitney U test). A P value of < 0.008 was considered statistically significant for such comparisons between any two groups after Alpha adjustment.
