Three approaches were tested to perform a first-order SA on such a model, assuming a fixed model structure and no correlation among input variables: (i) factorial designs combined with analysis of variance (ANOVA), (ii) conditional probabilities, (iii) Monte Carlo sampling (MC).
For this reason, we favor an estimation of the standard deviation using a curve-fitting technique rather than a fixed model based on previous data.
In order to mitigate this effect, where a fixed model was chosen on the basis of a lack of evidence for heterogeneity, corresponding results for a random effects analysis (not included here) were generated for comparative purposes.
Also, previous meta-analysis preferentially reported on a fixed effect model instead of the more conservative random effect model, which is more appropriate here owing to considerable study heterogeneity.
Therefore, when between-subject variations in outcome trends are anticipated to be significant, sample size determinations based on a fixed slope model can result in a seriously underpowered study.
If several risk estimates were available from one study (for example, separate results for men and women or for current and former use), we combined them by carrying out a meta-analysis based on a fixed effect model.
We calculated pooled odds ratios based on a fixed-effects model (Mantel–Haenszel method) and a multiple logistic regression model.
The pooled estimate was based on a random-effects model if the between-study heterogeneity was statistically significant; otherwise it was based on a fixed-effects model (9).
The pooled prevalence estimate of PAH in patients with lupus was 3.34 % (95 % CI, 2.10%to 4.86 %) based on random-effects model and was 3.24 % (95 % CI, 2.26 % to 4.38 %) based on a fixed-effect model (Fig. 3) Two studies reported prevalence of PAH in patients with rheumatoid arthritis ranging from 21%to27.5%.5 %.
