Trend analysis revealed an overall significant (P < 0.001) increase in the proportions of HBsAg positive donors from 1998 to 2002 for combined data and for the data from blood bank I.
The enigmatic finding of a negative correlation of the proportion of phytic acid-P and total foliar P in a recent review was based on combined data from several studies and could well have been fortuitous.
From an assessment of the combined data, it was concluded that even with dietary proportions below 3% MCFA of C12 0 and C14 0, a 50% reduction of in vivo methane emission is possible.
Using the combined data, the proportion of sperm transferred from the SEV to SPV at copulation was estimated to be 8.4% (n = 16, SE = 4.2).
Next, we test if the proportion of nodes shared between the combined-data and mtDNA trees is correlated with the overall proportion of the variable sites in the combined data that are from mtDNA (given the prediction that the data set with more variable characters will have a stronger influence on the combined-data tree).
A conditional analysis was done in linear regression model to examine the independence of the four associated SNPs in the combined data (partial r indicated the proportion of the serum UA variation explained by each SNP).
As the data from GPRD did not distinguish between the proportion of combined oestrogen progestogen preparations that had been prescribed as continuous combined preparations, or cyclic combined preparations, it was assumed that these were in the ratio of 1 2, as in the Million Women study.
Of course, analysts have always cleaned and combined data.
* including the outgroup S. nicolai The proportion of unresolved and partially resolved quartets is shown for phylogenies based both on single gene fragments, and on the combined data.
The combined data were analyzed using three partitions (nuclear, plastid, gap data), allowing partition models to vary by unlinking gamma shapes, transition matrices, and proportions of invariable sites.
In addition to these studies, there were a proportion of trials that were not used to combine data in the quantitative analysis.
