About

Bayes' post

This medical app calculates the probability of a disease after a diagnostic test. It uses pre-test probability, test sensitivity, and specificity to determine post-test probabilities for both positive and negative results.

Highlights
  • Calculate post-test probability
  • Input pre-test probability
  • Use test sensitivity
  • Use test specificity
  • Analyze positive results
  • Analyze negative results

Read full description

This clinical decision-support app is intended for use by healthcare professionals and unifies two cardiovascular prevention tools: the 2013 ACC/AHA Pooled Cohort Equations (previously known as the ASCVD Risk Estimator) and the American Heart Association’s PREVENT™ Calculator. Combining traditional ASCVD risk modeling with modern cardiovascular-kidney-metabolic (CKM)-inclusive risk equations, CVD Risk Estimator Plus supports comprehensive, personalized cardiovascular disease (CVD) risk assessment and clinician-guided decision-making. The results and recommendations provided by this application are intended to inform but do not replace clinical judgment. Therapeutic options should be individualized and determined after discussion between the patient and their care provider. CVD Risk Estimator Plus computes risk estimates using: • 2013 ASCVD Pooled Cohort Equations (PCE), which calculate 10-year and lifetime risk of atherosclerotic cardiovascular disease using age, sex, race, blood pressure, cholesterol profile, diabetes status, and smoking status. • 2023 PREVENT™ Equations, which estimate 10- and 30-year risk for total CVD, ASCVD, and heart failure (HF), incorporating kidney and metabolic health measures such as BMI and estimated glomerular filtration rate (eGFR), and supporting optional predictors including urine albumin creatinine ratio (UACR), hemoglobin A1c (HbA1c), and social deprivation index (SDI). Clinicians can toggle between Pooled Cohort and PREVENT™ risk trajectories to support guideline-aligned prevention discussions. This clinical decision support app provides: • Risk category classification (low, borderline, intermediate, high). • Personalized guidance informed by published guidelines, including statin therapy considerations, lifestyle interventions, and risk-enhancing clinical factors. • Export functionality supporting print and email of results for documentation and patient communication. • Resources page with related tools and informational materials for clinicians and patients, including links to source guidelines and reference documents.

Verdict

The call

The clearest difference is rating: CVD Risk Estimator Plus at 5.0 against Bayes' post's 3.7. CVD Risk Estimator Plus also leads on update cadence (every 4 months vs every 23 months). Bayes' post's advantage is review sentiment (50% vs 32%) and ratings volume (3 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
