Strict standardisation of the methodology used to measure physical activity and the fact that all women were compliant with the measurement procedures is one of its strengths.
A detailed description of the PEA POD's physical design, operating principles, validation and measurement procedures is provided elsewhere [16], [17].
A detailed description of the PEA POD's physical design, operating principles, validation and measurement procedures is provided elsewhere [ 38, 39].
The identification of precise and replicable measurement procedures is another of the requirements that have demonstrated to be useful in reducing the methodological heterogeneity of the present results.
As detailed information of all used techniques was published by our group [ 3, 6, 27, 34] only a description of the essential aspects of the different measurement procedures is given.
The main strength of the present study (along with the relatively larger sample size and repeatability of measurement procedures) is the application of available built-in software, enabling automated segmentation and thickness measurements of retina, GCC/GCIPL, and choroid.
