To account for uncertainty imposed by pregnancy and blood sampling, a 20% allowance was added to the estimated sample size, thus 19 women were originally planned for recruitment.
This was based on a 95% confidence level, a ± 10% margin for error, a response distribution of 50% (which requires the largest sample size), and allowance of 10% for non-response and a conservatively estimated design effect of two.
Firstly, we examine a simple non-chance-corrected agreement score based on the observed proportion of agreements with the consensus for each sample, which makes no allowance for missing data.
From patient 16 onwards, the protocol was amended again to include an additional two samples for M30/M65 analysis at day 8 and 15 (five samples in total) from the first cycle and an allowance to collect samples from subsequent cycles of OXi4503 treatment.
The residual sample weight after ashing, with allowance for the original moisture content of the STP, provided an estimate of the STP's inorganic content.
The study made no allowance for multiple sampling of the same family, but the aim was to assess the burden of cancer genetics in a GP practice.
Our archival results find that no firms made a SAB 108 adjustment and while sample firms tend to, at best, make small reductions to the allowance subsequent to SAB 108's effective date, most sample firms continue to have potentially overestimated allowances several years later.
With a 10% allowance for missing data, a sample size of 96 was obtained for this study.
With a 15% allowance for attrition, the adjusted sample size is 268 (i.e. 228/ 1-0.15)).
The minimum sample size was computed as 183, after allowance for a 5% non-participation rate.
This study used 90 participants (sample estimate of 2x40 [ 24] plus allowance for missing data) in a between-subjects experimental design.
