Blueprint for modelling time effects in a stepped-wedge, cluster-randomised trial

# Project title Blueprint for modelling time effects in a stepped-wedge, cluster-randomised trial # Brief project overview This is Data coming out of the IPOS-Dem project, a Stepped-wedge Cluster Randomised Trial (SW-CRT). Please make shure to check out the SW-CRT protocol for more details at https://www.doi.org/10.1111/jan.14953. We are currently working on our main study (SW-CRT) analysis. While we remain dedicated to open science, our priority is to ensure the utmost integrity of our ongoing research. # Contributors Frank Spichiger, Andrea Koppitz, André Meichtry ## Repository overview |-- readme.md |-- documentation |--readme.md |--Datadictionary.html |-- data |--readme.md |--IPOS-Dem_CH-SW-CRT_PLD_Qualidem.feather |--IPOS-Dem_CH-SW-CRT_PLD_locf_Qualidem.feather |--csv |--IPOS-Dem_CH-SW-CRT_PLD_Qualidem.csv |--IPOS-Dem_CH-SW-CRT_PLD_locf_Qualidem.csv |-- analysis |--readme.md |--240229_Analysis_Main.html |--240229_Analysis_Main.qmd |--grateful-refs.bib |--output |--models-REML.csv |--models.csv |--figures |--Conversions for plotting - 1.png |--Define Model 5-1.png |--Defining Model 4-1.png |--m1predictions.eps |--m1predictions.png |--m2predictions.eps |--m2predictions.png |--m3predictions.eps |--m3predictions.png |--m4predictions.eps |--m4predictions.png |--m5predictions.eps |--m5predictions.png |--Model 1 plot-1.png |--Model 1 plot-2.png |--Model 2 plot-1.png |--Model 2 plot-2.png |--Model 3 plot-1.png |--More plots for Model 1-1.png |--More plots for Model 1-2.png |--More plots for Model 4-1.png |--More plots for Model 5-1.png |--Plots for Model 4-1.png |--Plots for Model 5-1.png |--Plots for the other two models-1.png |--Plots for the other two models-2.png # Applicable instructions The R markdown files were generated using R 4.2.2 in RStudio 2023.12.1 for MacOS X you can run them using free software but will need to install R, Rstudio and the packages cited at the end of the quarto or the rendered html we used. # Additional resources - Main study protocol: https://www.doi.org/10.1111/jan.14953 - QUALIDEM measure used: https://doi.org/10.1186/1477-7525-11-91 - Pos-Pal consortium with more information on the measure: https://www.pos-pal.org - IPOS-Dem translation and adaption: https://www.doi.org/10.1186/s41687-022-00420-7 - IPOS-Dem inter-rating reliability: https://doi.org/10.1371/journal.pone.0286557
