Table 1 Methodological differences between AusDiab and DRUID studies
From: High rates of albuminuria but not of low eGFR in Urban Indigenous Australians: the DRUID Study
Measure | AusDiab | DRUID |
|---|---|---|
Blood Pressure | Dinamap semi-automatic oscillometric recorder | Welch Allyn Spot Vital signs monitor |
HbA1c* | Boronate affinity high-performance liquid chromatography (BioRad Variant Haemoglobin Testing System, BioRad, Hercules, CA, USA) | Percentage of total haemoglobin after separation by ion-exchange chromatography on a Pharmacia Mono-S column (results traceable to DCCT method) |
Serum creatinine | Modified Jaffe reaction (Olympus AU600 auto-analyser)** | Kinetic Jaffe (Hitachi 917) |
eGFR | Estimated from calibrated serum creatinine values, using the "175" MDRD equation | Estimated from pre-IDMS creatinine values, using "186" MDRD equation |
Urine albumin | Immunonephelometry (Beckman Array) | Immunonephelometry (Beckman array 360) |
Urine creatinine | Modified Jaffe reaction (Olympus AU600 auto-analyser) | Kinetic Jaffe (Hitachi 917) |
CRP | Data unavailable, therefore CRP not included in comparative model | Â |
