It is true that the sampling system did not provide us with subsequent texts that possibly are currently available, but the explanatory nature of the study should focus on whether to use resources in a similar research on a larger sample based on the results obtained.
In this study we are able to justify the use of a single reference sample based on the results of an ANOVA analysis of the batch adjusted data.
The questionnaire was slightly refined for wording and format before distribution to the study sample based on the results of the pilot study.
We assigned a true value to that reference sample based on the results obtained in the last 25 VL runs per assay: the mean VL SD was 3.13 0.12 (Siemens), 3.18 0.07 (Abbott) and 3.37 0.08 log10 cop/mL (Roche).
Ancestry was assigned to a sample based on the result of the majority vote.
As V = 4 3 π r a r b 2 and S = 2 π r b ( 7 3 r a 2 + 2 3 r a r b + r b 2 ), where r a and r b are the length and outer diameter of the Fe3O4 NPs, the density of the sample based on the BET result is estimated to be 2.16 g cm-3), it is smaller than 5.18 g cm-3 for corresponding bulk Fe3O4, which indirectly proves that the Fe3O4 NPs are in porous.
Our results indicate that in our case with more than 10 class compounds, the control sample based normalization did not improve results relative to a simple median normalization.
The density of the sample based on the current BET result is calculated to be 2.16 g cm-3 (Assuming that each Fe3O4 NPs is an ellipsoid, thus ρ = M V, and M = A s · S, where ρ is the density of the sample; M, S and V are the mass, surface area and volume of one Fe3O4 particle, respectively; A s is the BET surface area of the sample.
The resulting study sample, based on the more traceable and less mobile, was somewhat less diverse than our target population, although it did appear that oversampling of those in the lowest education groups was helpful.
Because birth weight may vary greatly for infants at a comparable gestational age, selecting a sample based on gestational age could result in a wide spread of birth weights.
In addition to the results related to precision for sampling based estimates, their results showed that ALS data provided the best plot level models for AGB (R2 = 0.64) followed by high resolution satellite images from RapidEye (R2 = 0.53).
