Abstract

fetched live from OpenAlex

PURPOSE: Systemically administered anticancer vascular endothelial growth factor inhibiting therapies can cause severe kidney injury. Intravitreal aflibercept has a greater impact on renal vascular endothelial growth factor levels than ranibizumab. We compared the risk of kidney injury among patients receiving intravitreal aflibercept versus ranibizumab. METHODS: This population-based new-user active-comparator cohort study in Ontario, Canada, evaluated 44,571 patients aged 66 years and older, newly treated with intravitreal aflibercept or ranibizumab between August 1, 2015, and July 31, 2019. The risk of adverse renal outcomes was compared while controlling for baseline and time-varying covariates. RESULTS: The composite renal outcome occurred in 12.0% (1,778/14,863) of aflibercept recipients versus 10.0% (1,327/13,289) of ranibizumab recipients (relative risk: 1.00, 95% CI: 0.93-1.06 at the 5-year follow-up). No significant differences were observed across retinal disease subgroups. CONCLUSION: Intravitreal aflibercept and ranibizumab carry comparable risks of renal adverse events despite their distinct systemic pharmacodynamics.

Full frame distilled prediction

Teacher imitation

Not 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.
