**Files in /Source data**
- `Group raw data tables.xlsx`: This workbook contains tables of study characteristics, participant characteristics, outcome data summary statistics extracted from source articles, and other information coded as part of the systematic review of group design studies.
- `SCD raw data tables.xlsx`: This workbook contains the raw data tables of study characteristics, participant characteristics, raw outcome data extracted from graphs in source articles, and other information coded as part of the systematic review of single-case design studies.
**Files in /R code**
- `1-Calculate effect sizes.R`: This script includes codes for calculating within-case effect size estimates for included single-case design studies. It saves the output in `Effect size estimates (within-case).xlsx`.
- `2-Clean covariates.R`: This script cleans the participant characteristics, instructional contexts, and communication outcomes covariates for included single-case design studies. It saves the outputs in three spreadsheets in `SCD covariates data tables.xlsx`.
- `3-Clean covariates for group designs.R`: This script cleans the participant characteristics, instructional contexts, and communication outcomes covariates for included group design studiess. It saves the outputs in three spreadsheets in `Group covariates data tables.xlsx`.
- `4-Calculate effect sizes for group designs.R`: This script includes codes for calculating summary effect size estimates for included group design studiess. It saves the output in `Group effect size estimates.xlsx`.
- `robust-metafor.R`: This script includes helper functions for fitting meta-analytic models.
**Files in /Cleaned data**
- `Effect size estimates (within-case).xlsx`: Cleaned effect size estimates for included single-case design studies.
- `SCD covariates data tables.xlsx`: Cleaned covariate data for included single-case design studies.
- `Group effect size estimates.xlsx`: Cleaned effect size estimates for included group design studies.
