Network meta-analysis results with corresponding GRADE (grading of recommendations, assessment, development, and evaluation) certainty of evidence for work-specific sitting time reduction. Values correspond to the standardized mean difference (SMD) in work-specific time reduction between columns and rows: for negative values, the intervention indicated in the row may be better for reducing work-specific sitting time (e.g., the sit-stand workstation group had a work-specific sitting time reduction compared with the typical desk group; SMD =  − 1.10). Values in bold indicate a statistically significant treatment effect. N indicates the number of studies used for the comparison. Results without N in the boxes are derived through the process of indirect comparison in network meta-analysis
