We judged all trials to be at low risk of reporting bias; no evidence for selective outcome reporting was retrieved in any of the included studies when comparing abstract, methods, and results section [36, 37, 38, 39, 40].
Furthermore, time of day can also have an important impact on the outcome of studies when comparing different experimental groups.
Note that this method is distinct from the ANOVA commonly used in biological studies when comparing two or more groups of experimental data.
Our findings are consistent with the results from most studies when comparing local growth charts with the WHO growth standards in estimating the prevalence of underweight.
We include the 23 males so that we can use the same control group for later studies when comparing other disease controls.
Differences were observed among studies when comparing our findings with previously published results and parts of the reason might be due to the ethnic heterogeneity, such as varied effect allele frequencies and unique LD structures.
The difficulty in recruiting to randomised controlled studies when comparing treatments for prostate cancer has been demonstrated with the latest cryosurgery vs radiotherapy randomised controlled trial that failed to recruit (Donnelly et al, 2007).
Substantial heterogeneity was observed among studies when comparing the efficacy of PDT and anti-VEGF, which was not surprising, given the differences in the various matching criteria and non-standardized measurement of outcomes.
As has been observed in other studies, when comparing perpetrators of femicide with other abusive men, unemployment appears to be a significant demographic factor even after controlling for other relevant characteristics [ 17– 17].
The median 24UV was in line with prior studies when comparing with previously published population-based data showing a median urine volume of 1.8 L in 2148 participants of a prospective cohort study undertaken in Canada [ 3].
Also, the introduction of new and potentially bone loss-protective treatment cohorts must be accounted for in more recent early RA studies when comparing them with the Lund early RA cohort treated according to the clinical standards used over 25 years ago.
