*Studies may have reported measuring additional types of fit in different aspects of the person–environment paradigm (eg, Rehfuss et al 51 measured needs–supplies and demands–abilities person–job fit).51 These are not relevant to the aims of this systematic review and are not reported here.
†The total number of articles measuring supplementary fit does not equate to the number of studies measuring each individual component of supplementary fit, as some studies measured multiple components of supplementary fit in one study.
‡The total number of articles measuring P-O fit does not equate to the number of studies measuring each individual component, as some studies measured multiple components of P-O fit in one study.
