Abstract
AIMS: The IMPROVE observational study evaluated the safety profile and effectiveness of biphasic insulin aspart 30/70 (BIAsp 30) in patients with type 2 diabetes in routine practice in 11 countries. METHODS: Patients who initiated insulin therapy with, or switched existing insulin therapy to, BIAsp 30 in routine care were eligible for this 26-week, non-interventional observational study. Data on adverse events, hypoglycaemia and glycaemic parameters were obtained from patients' diaries and medical notes. Questionnaire-based patient treatment satisfaction was also measured. We report global results and, uniquely for a diabetes observational study, country-specific data. RESULTS: A total of 52,419 patients were enrolled from three prestudy treatment groups: no pharmaceutical therapy (n = 8966, diabetes duration 2.0 years, baseline HbA1c 9.9%), oral antidiabetic drugs (OADs) only (n = 33,797, diabetes duration 7.4 years, baseline HbA1c 9.2%) and insulin +/- OADs (n = 9568, diabetes duration 10.4 years, baseline HbA1c 9.3%). At final visit, HbA1c, fasting and postprandial blood glucose were significantly reduced from baseline in all subgroups (no pharmaceutical therapy: -3.1%, -5.9 and -9.0 mmol/l, respectively; OADs-only: -2.1%, -4.1 and -6.1 mmol/l; insulin +/- OADs: -2.0%, -3.3 and -5.1 mmol/l). Major hypoglycaemia rates decreased in all subgroups; minor hypoglycaemia increased in the insulin-naïve groups. There was no mean weight gain across subgroups. Across all countries, glycaemic parameters and major hypoglycaemia were reduced; weight increases were seen in some countries. Treatment satisfaction increased in all subgroups and countries following BIAsp 30 therapy. CONCLUSIONS: Initiating insulin with, or switching insulin therapy to, BIAsp 30 in routine care resulted in improved glycaemic control, reduced major hypoglycaemia and greater treatment satisfaction.

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
