This is possibly due to the slight differences in the correlations among the factors in the English and Filipino versions.
However, a gamma-alumina containing 3.9% weight sodium and ca. 2.8×1014 sites/cm2 displayed a much lower activity than expected from the correlation, possibly due to the presence of strongly basic sites which lead to the formation of non-reactive adsorbed SO2 species.
Although the distribution was high, possibly due to the heterogeneous GOLD II population, the correlations were strong and significant.
However the only significant correlation found in the current study was between soil exchangeable Sr (Additional file 1: Table S1) and granule Sr (r = 0.70, p ≤ 0.05, Rank Spearman correlation), possibly due to the restricted range of soil concentrations used, or the use of real soils.
(The other three cohorts did not show significant correlation, possibly due to the low frequency of the alternative allele, thus lower power).
In rural areas, we found lower correlation possibly due to the low HIV prevalence in the rural communities [ 13] and a lag period between the spread of HIV infection and maturity of the epidemic.
We found that, for lowly expressed genes, the correction for expression level abolished the correlation (fig. 3), possibly due to the bias discussed earlier.
However, we could not confirm the correlation between the mutations and clinical response, possibly due to the retrospective approach and small number of samples.
Likewise, Laanen et al. [ 9], identified a positive correlation between cleaning and daily weight gain, possibly due to the reduction of gastrointestinal disorders.
For those variables showing approximate normal distributions, correlations were all not significant (Table 1), possibly due to the heterogeneity in the distribution of the change across the branches (Additional file 8) or the limited number of branches involved [ 33].
