Abstract

fetched live from OpenAlex

Diabetic retinopathy (DR) is the most common complication of diabetes and the leading cause of vision loss worldwide. Clinical detection relies on the manifestation of sight-threatening microvascular, macrovascular and edematous ocular insults. However, preclinical investigations detected retinal thickness irregularities. We hypothesized that retinal thickness irregularities are localized to specific retinal regions and layers. Training and validation data were collected from participants with diabetes with no/minimal DR and healthy individuals to identify and verify regions of interest. Optical coherence tomography and MATLAB速 computing were the primary tools used to measure retinal thickness in each participant. Linear mixed-effects models identified four significant regions of thickness irregularities from the training data; these were not matched by validation data. Nonetheless, retinal thickness irregularities were localized to specific regions and layers. Recognizing that there are retinal regions susceptible to retinal thickness irregularities during preclinical stages of disease is important for early disease detection.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
