k=number of independent study samples.
n=total sample for all contributing studies.
Positive effect in regard to visit duration indicates accompanied visits longer; in regard to verbal activity positive effect r indicates that dialogue for patient, patient and companion, and physician represent a greater proportion of visit dialogue during accompanied relative to unaccompanied visits.
P-value of Combined Z for weighted estimate. P-values are two-tail.
p<0.10 is considered evidence of substantial heterogeneity.
Contributing studies: Beisecker, Greene, Ishikawa, Jansen, Labreque, Street (visit duration); Ishikawa, Street, Shields (verbal activity).
Reflect average proportion of per-visit utterances (Ishikawa and Street) and mean words spoken (Shields).
