Abstract
Background: Quality of life (QoL) is commonly assessed in inflammatory bowel disease (IBD); the relationship of QoL within IBD states and relative to others has not been comprehensively evaluated. This systematic review, published across 2 papers, evaluates 5 key QoL comparisons. Part I, presented here, examines between-disease comparisons: (1) IBD/healthy(general) population and (2) IBD/other medically ill groups. Part II examines within-disease comparisons: (3) active/inactive disease, (4) ulcerative colitis/Crohn's disease, and (5) change over time. Outcomes using generic vs IBD-specific QoL measures were also examined. Methods: Adult and pediatric studies were identified through systematic searches of 7 databases from the 1940s (where available) to October 2015. Results: Of 6173 abstracts identified, 466 were selected for final review based on controlled design and validated measurement; 30 unique studies (23 adult, 7 pediatric) addressed the between-disease comparisons. The pooled mean QoL scores were (1) lower in adult and pediatric IBD samples compared with healthy controls (n = 19), and for both mental and physical QoL, where measured; and (2) higher but not significant for those with IBD compared with various medically ill controls (n = 15). Findings were consistent across IBD-specific and generic QoL measures. Study quality was generally low to moderate. The most common measures of QoL were the disease-specific Inflammatory Bowel Disease Questionnaire and generic SF-36 (adults), and the generic PedsQL (children). Conclusions: There was robust confirmation that QoL for individuals with IBD was poorer than for healthy individuals, for both adults and children. QoL in IBD may be better relative to some other gastrointestinal (GI) and non-GI medical conditions for children.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
