Some of the analyses focused on the five most prevalent diagnostic groups, to gain more statistical power.
For some of the analyses, it was appropriate to analyze only subsamples instead of the full sample.
The uptake of the non-targeting ligand was subtracted from that of the targeting ligand as a measure of specific uptake in some of the analyses.
Regarding the type I error, in some of the analyses the α-levels were Bonferroni corrected, since the items supposedly measured the same construct.
For each of the sites in this study, some of the analyses were limited by sparseness or ambiguity in the data sets.
There was an evident discrepancy between some of the analyses in estimating multiplicity of HIV infection.
In some of the analyses, Spiniferodinium and Akashiwo were also part of this athecate assemblage (Figures 3, 4).
A participant's normalized brain volume at baseline was used as a covariate in some of the analyses.
We thank Mark Patterson, Richard Cave and Theodora Bloom for helpful comments on some of the analyses described in this manuscript.
We did repeat some of the analyses described in this paper on 49,747 clusters of sizes 10 19, which contain 971,171 ORFs.
Some of the analyses, however, may not be appropriate for use with particular data sets, or for particular regions or time periods within a dataset.
