Blood pressure was assessed by a trained research nurse using a digital calibrated sphygmomanometer with appropriately sized cuffs (Omron HEM-907, JA Davey Pty Ltd).
Systolic and diastolic blood pressures were measured by trained clinic research assistants using a digital automatic blood pressure monitor (Dinamap model Pro Series DP110X-RW, 100 V2; GE Medical Systems Information Technologies, Inc., Milwaukee, WI), after the subject was seated for at least 5 minutes.
To assess for intra-rater reliability, at the end of each HD session during the run-in phase, the dialyser quadrants are captured in four photographs by the same trained research nurse, using a digital camera on a tripod, with standardised lighting, at a standardised distance and height from the dialyser.
All slides were visualised using a Leica RMDB research microscope and images captured using a digital camera and Bioquant Nova image analysis system.

At the first prenatal visit, trained research staff measured the women's height using a digital stadiometer (Charder HM200P Portstad Portable Stadiometer, USA).
The FGD proceedings were audio recorded using a digital voice recorder, transcribed and translated into English language by two experienced research assistants, fluent in both Dholuo and English.
One research assistant facilitated/conducted the FGD/ interview, while the second one recorded the session using a digital voice recorder.
using a digital thermometer.
