Data Synthesis
Studies were organized into tables and categorized based on the proportion of the sample with ABI. The following three categories were used: <50% ABI, >50% ABI, or unknown. These three groupings were used to separate studies to clarify the number and type of interventions studied with a uniquely homogenous ABI population, mixed heterogenous stroke and ABI population, or proportion unknown population, respectively. This is to aide in transparency of the research literature with respect to dysphagia interventions in ABI.
