Schematic representation of population and experimental procedure of included studies. Colors are used to indicate mentioned information in each study (orange: population; light grey: sex; dark gray: BMI class; red: outcomes; green; settings; yellow: device positioning; blue: filtering methods). Within the same category, blank cells mean that the information was not mentioned. BMI: body mass index; LFE: low-frequency extension; MAVM: moving average vector magnitude; NF: normal filter.
