22 In addition, for precision of outcomes, we chose the narrow range of difference (±0.5 point) in main outcome after treatment, and we used the t-test for noninferiority to determine effect between groups.
In spite of improvements in implant designs and surgical precision, functional outcomes of mechanically aligned total knee arthroplasty (MA TKA) have plateaued.
To determine the influence of age and the corneal stromal refractive index on the difference between the predicted and actual postoperative refractive error after laser in situ keratomileusis (LASIK) and whether the precision of outcomes could be improved by considering age and the refractive index.
Given the recruitment and follow-up challenges associated with individuals in this population, researchers can attempt to maximize statistical power by increasing actual effect size, decreasing sample variability, and increasing precision of outcome measurements.
The developments in neuroimaging during the last decades have led to remarkable improvements in surgical precision, postsurgical outcome, prognosis, and the rate of seizure control in patients with TLE.
Study DIAD judges quality in four categories, namely the fit between concepts and operations, the clarity of causal inference, the generality of findings, and the precision of outcome estimation.2 The rating measure is a weighted mean of the four areas with a value between 0 and 1.
Also, the measurement precision of outcome measures along the scale was only evaluated occasionally.
Also, the measurement precision of outcome measures along the scale has only been evaluated occasionally.
The results are presented in odds ratio (OR), confidence interval 95% (CI) and also Nagelkerke, R, for model precision of outcome.
The main shortcoming of this pilot study is the small sample size which is reflected in the low statistical power and precision of outcome measures.
This probably resulted in reduced precision of outcome data (ECG may underestimate LVH in obese subjects) that reduced the power of the analyses but probably was not likely to introduce a systematic bias.
