However, the use of different procedure classifications is not the only obstacle in the harmonisation of DRGs: the local applications of standardised disease classifications, such as the ICD-10 are also known to vary across European countries [ 3].
In addition to ethnic differences, the variation in prevalence rates may be due to the use of different screening procedures and diagnostic criteria, how long back the studies were done, maternal age, parity, pre-pregnancy weight and BMI, and whether the studied population reside in urban or rural areas.
The catalytic behavior was entirely different for each of the as-developed metal-support interface, derived in by the use of different synthesis procedures.
Using CFD analysis we compared the use of different PCI procedures, with and without the utilization of a proximal optimization technique (POT), on a complex coronary artery bifurcation.
That is why he gave an accurate description of prospective and nonprospective papers in a chronologic order, underlying the limitation of the study due to the lack of validated outcome measures, and the use of different surgical procedures that are seldom used today.
The value of the RAH diameter was highly variable in the literature, due to the use of different measuring procedures.
The data obtained on mouse brain sections using TEM are not in accordance with those obtained on cultivated mammalian cells by conventional immunofluorescence technique with the use of different fixation procedures and less microscope resolution.
The heterogeneity may be increased by a number of research methods such as: 1) different features of the study design in the subgroup analyses of different studies, as well as the use of different surgical procedures and/or radiotherapy regimens; and 2) evaluation of potential confounding factors regarding disease progression.
These comparisons did not separate differences due to the use of different data preprocessing procedures from differences due to the use of different peak calling procedures, and both these differences were not separated from differences caused by using different probe mapping library files (i.e. BPMAP files).
