The rationale for choosing alternatives used for comparison was made only implicitly by all studies except one [21].
Wilcoxon rank sum tests were a non-parametric alternative for comparisons with respect to quantitative or ordinal variables, and Fisher's exact test was an alternative to the Chi-square test in the presence of low expected frequencies in the chi-square calculations.
Due to violation of normality assumption, all statistical analysis regarding sickness absence, mental and physical health as well as bodily pain (at both 18-month and 36-month follow-up) were all done by Kruskal-Wallis 1-way ANOVA on ranks, as this non-parametric test is a suitable alternative for comparisons of three or more groups [ 24].
An alternative scheme for comparison with the proposed one is the equivalent DCA algorithm.
In practice, no solar cell experiences such conditions, yet few alternative bases for comparison exist [2].
An alternative scheme for comparison with the proposed one is an equivalent cooperative scheme, also with a unitary rate, though fully orthogonal.
This optimal current step-up practice according to an explicit consensus protocol is considered the best alternative available for comparison to early surgery.
Alternative trees for comparison were found based on RAxML searches (with gene partitions as detailed previously), but with the tree topology constrained to reflect the alternative hypothesis of choice (e.g., constrained for clade III monophyly).
An alternative way for comparison is to assess the significance scores of PTM pairs previously reported as highly correlated [ 52]. [ 11] developed a biclustering method to search for combinatorial patterns of PTMs on the same data.
An alternative dataset for comparison with foetal PM ADC values would be antenatal foetal body organ and lung MRI, but these were not available at the time of this study.
