Using similar analyses, we split this outcome into of people who had been admitted on one occasion only (e-r /n and those-r /nhandmulthose admissions as a proportion of the denominator population (r/n).
In our subgroup analyses, we split dietary vitamin E and C levels, and the residual of fruit, vegetable, and berry consumption, at rounded levels close to the medians.
In our subgroup analyses in Tables 2 and 3, we split the subgroup variables at levels leading to a reasonably similar number of cases in the control groups.
For further analyses, we have split the adjusted per capita income into quintiles, calculating the quintile limits for each country separately.
Before beginning a series of factor analyses, we randomly split the sample groups in half (Group 1, n = 739; Group 2, n = 738).
It was only subsequent and separate analyses that split the cohort by work location that led to the conclusion of "an increased risk of lung cancer in both underground and surface workers".
Also in contrast to the rDNA phylogenies, the FA analyses split the genus Lobochlamys, i.e. L. culleus was part of the " Chloromonas" group while L. segnis belonged to the " Reinhardtii" group.
The phylogenetic and network analyses split the range-wide data set for the mitochondrial Cytb into two distinct phylogroups (clades W and E) separated with 1.6% of genetic distance (Fig. 3E,F), translating to a divergence time of about 64 × 10 to 1600 × 10 years ago.
For the purposes of analysing the explanatory variables we have split the groups in the four different categories of health care use as shown in Additional file 1. Fifty percent or more of the persons across all groups were overweight or obese.
In addition to running the interaction analyses with multiple regression, we chose to split the sample in two at the median IQ-score (103) to provide an illustration of the differences in the associations, or lack thereof, at different levels of intellectual ability.
