1. Using the 90th centile in the control group as the cut off, activin A was elevated in 72.2% of women with epithelial ovarian cancer, while follistatin was elevated in 11.2%.

2. Objective To construct age related centile curves, which can be read off as clinical references by a more flexible and more precise smoothing method to describe the numerical change with age.

3. Presented here is the age-related BMI centile curves for children aged 0-18 years in Shaanxi.

4. Age related centile of body mass index were fitted by using LMS method, function indexes and diathesis indexes were compared between higher BMI group and lower BMI group at same age and gender.

5. Overall severity of gastrointestinal symptoms influenced the final height centile as it had height velocity during the initial years of follow up.

6. Six of 10 with only such small bowel involvement were below the third centile for height when their disease was recognised.

7. Results Age related L, M, S curve were fitted and weight centile curves are presented.

8. Conclusions— Surrogate IR measures have modest performance at the 76th centile, with no threshold effects.
