Methodology & Clinical Sources
All calculation formulas, diagnostic thresholds, and patient educational guidance on BP Readings are strictly derived from peer-reviewed cardiology and endocrinology guidelines.
Core Editorial & Clinical Principles
Complete Integrity with Primary Guidelines
We never alter clinical cutoffs or invent proprietary stages. Our blood pressure classifications correspond strictly to Hypertension Canada and AHA/ACC guidelines, and our glucose thresholds mirror published standards.
Mathematical Rigor & Verifiable Formulas
Our A1C converter utilizes the peer-reviewed regression model established by the ADAG clinical trial. MAP and pulse pressure calculations reflect standard cardiovascular hemodynamics.
Plain-English Communication for Seniors
Medical information must be understandable to be useful. We translate intricate physiological mechanisms into accessible language with high contrast, large typography, and zero confusing medical jargon.
Primary Clinical References & Published Guidelines
Every threshold on bpreadings.com is cross-referenced against these landmark publications:
Hypertension Canada Comprehensive Guidelines & 2017 ACC/AHA Guideline
Whelton PK, et al. Journal of the American College of Cardiology (JACC) 2018;71(19):e127-e248.
Application: Defines diagnostic stages and cardiovascular risk management targets for adult populations.
Translating the A1C Assay Into Estimated Average Glucose Values (ADAG Study)
Nathan DM, et al. Diabetes Care 2008;31(8):1473-1478.
Application: Established the official linear regression formula: eAG (mmol/L) = 1.59 × A1C − 2.59 and eAG (mg/dL) = 28.7 × A1C − 46.7.
Diabetes Canada Clinical Practice Guidelines & ADA Standards of Care
Diabetes Care 2024;47(Suppl. 1):S1-S343.
Application: Defines diagnostic cutoffs: Normal A1C < 5.7%, Prediabetes 5.7%–6.4%, Diabetes ≥ 6.5%; Fasting normal 3.9–5.5 mmol/L.
Measurement of Blood Pressure in Humans: Scientific Statements
Muntner P, et al. Hypertension 2019;73(5):e35-e66.
Application: Standardized home blood pressure measurement protocol: 5 minutes rest, back supported, arm at heart level, multiple consecutive readings.
Review & Maintenance Cycle
Our clinical reference content is reviewed quarterly to ensure alignment with newly released clinical consensus statements and guideline updates.
