Abstract

fetched live from OpenAlex

Genetic predisposition is a risk factor for office hypertension. We sought to determine whether genetic predisposition identifies individuals with ambulatory daytime hypertension. 1444 participants from the GAPP study (ages 25-41) were analyzed. We evaluated two measures of predisposition to hypertension: family history and polygenic risk scores (PRS). We evaluated correlation of predisposition with blood pressure traits and compared incremental value of each predisposition measure to a validated ambulatory BP prediction model. 12% of participants had office hypertension, while 37% had out-of-office hypertension. The correlation between PRS and family history of hypertension was low (R2 = 4.96x10-3), but both were strongly associated with ambulatory blood pressure (2.2 mmHg per 1 SD increase [95% CI: 1.6, 2.7] & 2.4 mmHg increase with positive family history [95% CI: 1.3, 3.4], respectively). PRS provides incremental improvement predicting ambulatory systolic blood pressure beyond a validated blood pressure prediction score (ΔAIC = -33), whereas family history does not (ΔAIC = 1). The difference between a baseline prediction algorithm for identifying ambulatory systolic hypertension (positive likelihood ratio of 6.87 [95% CI: 5.56, 8.49]; negative likelihood ratio of 0.45 [95% CI: 0.39, 0.51]) and the same model with PRS integrated (positive likelihood ratio of 7.69 [95% CI: 6.18, 9.57]; negative likelihood ratio of 0.43 [95% CI: 0.37, 0.49]) was modest. In a white European sample from Liechtenstein, PRS provides incremental information in identification of individuals with ambulatory hypertension, unlike family history. However, these gains are modest and warrant further development to improve predictive utility at the point-of-care.

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.
