Shift table: Comparing 25OHD baseline measurement values with measurements at each later time point – intra-individual analysis of complete cases only

Time point	na	Decrease (n; %)	No change (n;%)	Increase (n;%)
Baseline	83	-	-	-
Immediate p/o	57	13 (22.8%)	43 (75.4%)	1 (1.8%)
3 months p/o	44	13 ( 29.6%)	20 ( 45.4%)	11 ( 25.0%)
6 months p/o	17	11 ( 64.7%)	2 ( 11.8%)	4 ( 23.5%)
12 months p/o	5	3 ( 60.0%)	1 ( 20.0%)	1 ( 20.0%)

Jonckhere-Terpstra test for change over time p = 0.0743. The last value (12 months p/o) was not included in statistical analysis because of too small numbers

p/o postoperatively

^aonly complete cases were included, i.e. those with serial measurements available
