Best Evidence Synthesis of Measurement Properties of the RMDQ and ODI in Head-to-Head Comparison Studies Conducted in Patients With Nonspecific Low Back Paina
↵a RMDQ=Roland-Morris Disability Questionnaire, ODI=Oswestry Disability Index, ?=unknown due to only studies of poor methodological quality or no studies on that measurement property, +/–=conflicting findings, +=consistent positive findings, –=consistent negative findings.
Responsiveness of the RMDQ and ODI in Studies Making a Head-to-Head Comparison in Patients With NSLBPa
↵a COSMIN=methodological quality assessment according to the COSMIN checklist, AUC=area under the curve (receiving operating characteristic analysis), LBP=low back pain, NSLBP=nonspecific low back pain, RMDQ=Roland-Morris Disability Questionnaire, ODI=Oswestry Disability Index, DRI=Disability Rating Index, SF-36-PF=physical functioning subscale of the 36-Item Short-Form Health Survey, NRS=numeric rating scale, VAS=visual analog scale, SF-RP-36=role–physical subscale of the 36-Item Short-Form Health Survey, SF-36-BP=bodily pain subscale of the 36-Item Short-Form Health Survey, GPCS=global perception of change scale, SRM=standardized response mean.
b Standardized response means were calculated by dividing the mean change by its standard deviation.
c These SRMs were calculated using the data presented in the review.
d These studies were included in the same article.
Characteristics of the 11 Studies and of the Patients Included in This Reviewa
↵a NSLBP=nonspecific low back pain; PD=pain duration; PL=pain localization; WS=work status; PM=pain medication; RMDQ=Roland-Morris Disability Questionnaire, score at baseline; ODI=Oswestry Disability Index, score at baseline; GP=general practitioner; NA=not applicable to the design of the study; NR=not reported.
b These studies were included in the same article.
c These studies were included in the same article.

Internal Consistency, Reliability, and Measurement Error of the RMDQ and ODI in Head-to-Head Comparison Studies Conducted in Patients With NSLBPa
↵a COSMIN=methodological quality assessment according to the COSMIN checklist, AD=assessment of dimensionality, ICC=intraclass correlation coefficient, SEM=standard error of measurement, SDC=smallest detectable change, NSLBP=nonspecific low back pain, RMDQ=Roland-Morris Disability Questionnaire, ODI=Oswestry Disability Index.
b Different ICC models were used (ie, Davidson and Keating38: ICC [2,1]; Grotle et al40: ICC [1,1]; Maughan and Lewis43 and Mousavi et al45: not clear which model or formula was used).
c Not clear whether SEMconsistency or SEMagreement was used.
d Different SDC formulas were used (ie, Davidson and Keating38: √[2×SEM]×1.64; Grotle et al,40 Maughan and Lewis,43 and Monticone et al44: SEM×2.77).
e These values are not presented in the review, but we calculated them from the data available.
