TASK: Your task is to answer biomedical questions using the given abstract. Only output yes, no, or maybe as answer.
INPUT: ['The aim of this study was to evaluate serum 25-hydroxyvitamin D (25OHD) concentrations in survivors of childhood cancer and compare levels by underlying diagnosis and as a function of time.', 'A retrospective review of 201 pediatric cancer survivors enrolled in a hospital-based cancer survivor registry. Demographic characteristics and 25OHD levels were extracted from the registry. Vitamin D status was determined during routine clinical care and was categorized as normal, insufficient, or deficient.', '25OHD levels differed significantly across diagnoses (P\u2009=\u20090.017), with the lowest levels found in patients treated for osteosarcoma, retinoblastoma, hepatoblastoma, and myeloid leukemias. Age was inversely correlated with 25OHD levels (P\u2009=\u20090.03). Average 25OHD level at study entry was 29.8\u2009ng/ml (range: 5-79.7), with 14.4% vitamin D deficient, 39.3% insufficient, and 46.3% normal. 25OHD concentrations decreased 11.4% over time (P\u2009<\u20090.00001).'] Do vitamin D levels differ by cancer diagnosis and decline over time in survivors of childhood cancer?
OUTPUT:
