We describe each individual study because comparison across all patient samples studied to-date is limited as a result of different measures of SES (insurance, income, and education) for stroke patients recruited from different settings (acute and rehabilitation care), and analysis of different outcome measures (Barthel Index and mRS) measured at different time points post-stroke.
Looking at the methodology of the studies the comparability is limited as the studies use different forms of economic evaluations (CUA [22 25, 30, 34 37], CEA [21, 26 29]) with (the resulting) different outcomes (QALY, DALY, BMI reduction, reduction in waist circumference,…).
However, comparison to those studies may be limited as they were conducted in different ages and different settings.
Major differences in study design, analytical methods, and the number and kinds of congeners measured make comparability (if any) between different studies limited, as recently discussed by some authors (Anger and Foster 2008; Heilier et al. 2008).
Comparison between all groups is limited, as each group received a different questionnaire adapted to reflect the findings of the systematic review [ 21] specific to each actual or potential user group.
Rovira et al. [ 2] mentioned that comparability of estimates on biosimilar-related savings is limited as the data are based on different modelling strategies and are dependent on the hypothesis used by different analysts.
However, the applicability of current animal models of parturition to the physiological mechanisms of human pregnancy and birth has been limited, as the means by which these different species regulate and initiate parturition differ from each other and from humans.
It is primarily a state based representation of intracellular gene activity; therefore it is limited as it does not include the different biological compartments involved in cholesterol metabolism, such as absorption, and hepatic/peripheral cholesterol synthesis.
Existing prevalence estimates based on dogs presented for primary practice care in the UK and USA are approximately three times higher [ 10, 11], however validity of comparisons with the estimate from this study is limited as these surveys were based on different methodologies for calculation of disease frequency measures.
South Korea's experience was different still, but also limited as a parallel to Iran.
