We sought to assess the long-term effects and potential heterogeneity of treatment effects over approximately 21 years of follow-up.<h3>Methods</h3>The DPP trial was continued with protocol modifications as the DPP Outcomes Study (DPPOS). In the DPPOS, placebo was discontinued, metformin (850 mg twice a day as tolerated) was continued after unmasking, and group-based booster intervention classes were offered to the ILS group twice a year; additionally, all participants were offered group-based lifestyle intervention four times a year. The prespecified primary outcome during DPP and DPPOS was diabetes incidence defined by American Diabetes Association criteria. The DPPOS protocol specified continued diabetes incidence as an outcome; Feb 23, 2020, was chosen as the closing date for the present analysis, as a date prior to the COVID-19 pandemic, which caused major disruptions in clinic visits and complicated longitudinal data analyses. We assessed long-term persistence of intervention effects on diabetes incidence, and heterogeneity of effects in subgroups defined by baseline diabetes risk factors. Follow-up is reported for the combined study from July 31, 1996, to Feb 23, 2020, and analysis was by intention to treat.

There is no validated initial laboratory assessment or diagnostic score to rule-in or rule-out arginine vasopressin deficiency during the first consultation. Therefore, this study aimed to evaluate the diagnostic potential of basal laboratory parameters and to develop a practical diagnostic score.<h3>Methods</h3>Data from two international multicentre studies of patients with arginine vasopressin deficiency and primary polydipsia undergoing the hypertonic saline test were used to evaluate the diagnostic potential of basal laboratory tests and to develop a score incorporating laboratory results, symptoms, and medical history. CODDI was a non-randomised, controlled, diagnostic, international, multicentre non-inferiority study in 11 tertiary medical centres in Switzerland, Germany, and Brazil. CARGOx was a randomised, controlled, cross-over, diagnostic, international, multicentre non-inferiority study across seven tertiary medical centres in Switzerland, Germany, the Netherlands, Italy, the UK, and Brazil. Participants were adult patients with polydipsia (>3 L per day) and hypotonic polyuria (>50 mL/kg bodyweight in 24 h and urine osmolality <800 mOsm/kg) and adult patients with a previous diagnosis of arginine vasopressin deficiency. Data were derived from the initial consultation and a basal laboratory test. For each laboratory parameter, the cutoffs resulting in the highest specificity at 100% sensitivity and the highest sensitivity at 100% specificity were identified. For the diagnostic score, the overall best cutoff, high-sensitivity cutoff (≥95% sensitivity), and high-specificity cutoff (≥95% specificity) were identified. Each cutoff was derived from the first study (development), and their performance was determined in the second study (validation). The final score included the sum of: basal plasma sodium multiplied by plasma osmolality, divided by 100; –50 points for plasma copeptin more than 4·9 pmol/L; +30 points for nycturia (≥3 times per night) or +20 points for nycturia (2 times per night); +20 points for sudden polyuria or polydipsia onset; +30 points for drinking more than 1 L per night; +50 points for anterior pituitary dysfunction and +50 points for pituitary surgery history. The diagnostic performance in predicting arginine vasopressin deficiency was examined by the receiver operating characteristic (ROC) area under the curve (AUC) and by sensitivity and specificity.
