Incident Renal Events and Risk Factors in Autosomal Dominant Polycystic Kidney Disease
Bibliographic record
Abstract
For determination of the incidence of renal events in autosomal dominant polycystic kidney disease (ADPKD) all patients who had ADPKD and attended nephrology/urology clinics in Newfoundland in 1981 were identified, and members of 18 families who were at 50% risk for inheriting ADPKD were followed prospectively for 22 yr, including research clinics at 6-yr intervals. Time to hypertension treatment, stage 3 chronic kidney disease (CKD), ESRD, and death was measured, and the impact of genotype, gender, gender of parent who transmitted PKD, family, family history of essential hypertension, parity, and oral contraceptive pill was assessed. Nine (50%) families had PKD1, four (22%) had PKD2, and one had both PKD1 and PKD2. The number of family members with PKD1 was 136 and with PKD2 was 60. In PKD1 median age to hypertension treatment was 46 yr, to CKD stage 3 was 50 yr, to ESRD was 53 yr, and to death was 67 yr. In PKD2, median age to hypertension treatment was 51 yr, to CKD stage 3 was 66 yr, to death was 71 yr, and ESRD was infrequent. Although the incidence of CKD was later and ESRD occurred infrequently in PKD2 compared with PKD1, early onset of hypertension occurred and life expectancy was compromised. Genotype, family, and proteinuria were identified as risk factors for incident renal events. Gender, gender of parent who transmitted PKD, family history of essential hypertension, multiparity, and use of the oral contraceptive pill were not identified as risk factors for renal events in ADPKD.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
