Data and do file

Data from four (published) web-based intervention trials used here to test methodological hypotheses

The following files simulate the data and run all models. Each do file takes arguments "nobs" and "effsize" to define the number of observations and effectsize - neg_contout_datsim (continuous outcome with no paternal effect) - neg_contout_datsim2 (continuous outcome with paternal effect) - neg_contr_datsim.do (binary outcome) Each of these uses "progs.do" to run the bootstrapping of the confidence interval of the difference in maternal and paternal effect estimates The separate datasets for each sample size and effect size are compiled into a single dataset using "compile_results.do". Statistics across simulations are calculated using the following files: - sim_cont_ready.do (continuous outcome with no paternal effect) - sim_cont_ready2.do (continuous outcome with paternal effect) - sim_bin_ready.do (binary outcome) The final datasets are included as the following .csv files: - neg_cont_simout (bias and other statistics for continuous outcome) - neg_cont_difs (mean and bootstrapped 95% CI of difference in estimates for continuous outcome) - neg_cont_simout (bias and other statistics for continuous outcome with paternal effect) - neg_cont_difs (mean and bootstrapped 95% CI of difference in estimates for continuous outcome with paternal effect) - neg_bin_simout (mean and bootstrapped 95% CI of difference in estimates for binary outcome) - neg_bin_difs (mean and bootstrapped 95% CI of difference in estimates for binary outcome)

The file final_data_27_04_2019.csv contains the final dataset used for all analyses in the paper "Overall bias and sample sizes were unchanged in ICU trials over time: a meta-epidemiological study" by Carl Thomas Anthon, Anders Granholm, Anders Perner, Jon Henrik Laake and Morten Hylander Møller. The file is provided as a comma-seperated values (csv) file. A data dictionary is provided in the electronic supplementary material (ESM) for the said publication. The file final_code.nb.html contains the final, annotated analysis code for the paper "Overall bias and sample sizes were unchanged in ICU trials over time: a meta-epidemiological study" by Carl Thomas Anthon, Anders Granholm, Anders Perner, Jon Henrik Laake and Morten Hylander Møller. The code is written in R and is provided as a Rmarkdown-notebook HTML-file. This file can be opened in a web browser and will display the annotated analysis code and the results, or in RStudio (www.rstudio.com), where it can be run and edited (https://bookdown.org/yihui/rmarkdown/notebook.html).
