We determine if classification systems improve patient-reported outcomes for people with low back pain (LBP).

Systematic review with meta-analysis.

MEDLINE, EMBASE, CINAHL, Web of Science Core Collection and CENTRAL were searched from inception to 21 June, 2021.

Reference lists of prior systematic reviews and included trials were screened.

We included randomized trials comparing a classification system (e.g. McKenzie and STarT Back Tool) to any comparator.

Studies evaluating participants with specific spinal conditions (e.g. fractures and tumors) were excluded.

Outcomes were patient-reported LBP intensity, leg pain intensity and disability.

We used the Cochrane RoB2 tool to assess risk of bias, and the GRADE approach to judge the certainty of evidence.

We used random effects meta-analysis with Hartung-Knapp-Sidik-Jonkman adjustment to estimate standardized mean differences (Hedges g) and 95% confidence intervals (95%CI).

Sub-group analyses explored classification systems, comparator type, pain type and duration.
