Various methods of sample preparation were compared: direct introduction of suspensions, ashing with microwave-assisted acid digestion, and microwave-assisted acid extraction, and their advantages and disadvantages evaluated.
The purified feCath preparation was compared to synthetic LL-37 by acid urea polyacrylamide gel electrophoresis (AU-PAGE) to assess homogeneity and confirm peptide concentration (Figure 5A, inset).
Ferric carboxymaltose, an intravenous iron preparation, was compared with placebo.
The time course of autophosphorylation of each mutant eEF2K preparation was compared with that of the wild-type.
Indices for paired biopsies (i.e those from the same patient, with and without preparation) were compared using the paired Student t-test.
The antioxidant properties of the seedcake preparation were compared to those of well-known water-soluble antioxidants (ascorbic acid, chlorogenic acid, caffeic acid) and SDG standard solutions.
For a more detailed analysis of the effect of e-module preparation, scores for stations which had e-module preparation were compared with the scores for stations which had text based preparation.
Of 14 studies providing data per type of oral contraceptive (web tables 5 and 6), at least one preparation was compared with non-use or two types were compared directly.
This was an open, randomised, two-period crossover trial in which the PK properties, tolerability and bioavailability of AS + AQ when administered as a fixed-dose or non-fixed dose preparation were compared.
Group comparisons for patient demographics, involvement of gastroenterology fellow, indication(s), type of bowel preparation and quality of bowel preparation were compared using the Chi-square statistic and 95% confidence intervals or the Student's t-test as appropriate for the distribution of each variable.
