With reference to the HDSS dataset, we selected 30 mothers with at least one child under 2 years old and who lived within approximately 2 km of two health centers in Kwale.
In each district, a severely flooded commune and a less affected commune (control commune) were selected with reference to the district's people committee; households were then randomly selected from the lists of households in each selected commune.
The high and low levels of these factors were selected with reference to the experimental domain that covers an interval of HLB from 7.8 to 15.
These thresholds were selected with reference to the natural variation of repeated movements demonstrated in an earlier study [ 32].
The frequencies and levels of two or more tones were selected with reference to the RF, to be used as probe tones.
The pragmatic sample size of 120 participants for the trial was selected with reference to the general rule of thumb recommended by Lancaster et al. [ 27], taking account of the factorial design of this exploratory trial and the primary and secondary outcome measures to be investigated.
With reference to the local analysis, laminate continuum elements were selected to discretize the skin and the stringer, whereas the adhesive was represented by interface cohesive elements to take the damage evolution into account.
We performed logistic regression analysis to evaluate the association between the incidence of hyperuricaemia and haplotype of the five selected SNPs with reference to the AGCAG haplotype.
Selected continuous variables were dichotomized with reference to the threshold maximizing the Youden Index (sensitivity plus specificity minus one) and then rounded to the nearest easy-to-recall value.
As the sensitivity of a surveillance system depends on the prevalence of infection in the population, evaluation needs to be performed with reference to a selected population prevalence of infection, or 'design prevalence' [ 30], which is specified at the infection status node of the scenario tree.
