PMID 42769602WHAT IT FOUND
People with disabilities in China who reported receiving rehabilitation services were more likely to be employed than comparable people who did not.
This cross-sectional survey cannot show the services caused employment.
Key findings
01After propensity score matching, receiving rehabilitation services was positively associated with employment (odds ratio 1.45; 95% CI 1.09 to 1.93; P=.01).
02By disability type, significant positive associations were found for physical disabilities (ATT 8.8%; 95% CI 0.8% to 16.3%; P=.025) and mental health conditions (ATT 15.8%; 95% CI 5.6% to 27.1%; P=.008), while visual, hearing/speech, intellectual, and multiple disability groups were not significant.
03By disability level, a significant positive association was found for level 3 (moderate) disabilities (ATT 22.1%; 95% CI 10.5% to 35.2%; P<.001), but not for levels 1, 2, or 4.

What it does not show
This was a cross-sectional survey, so it cannot show that rehabilitation services caused employment or track long-term effects. The survey did not collect details about the type, content, duration, or provider of rehabilitation services, so the contribution of any single component cannot be separated. Matching reduced the analysed sample to 512 people in each group (1024 total). Subgroup analyses further reduced the number in each stratum. Some subgroup estimates had wide confidence intervals, including the unmarried group (odds ratio 3.26; 95% CI 1.66 to 6.40). These estimates should be interpreted cautiously. The researchers excluded 30 questionnaires (1.6%). Missing data in those excluded records limited comparisons across many variables. The postmatching balance table reports employment in 21.1% of the rehabilitation group and 27.9% of the nonrehabilitation group, while the main logistic analysis reports an odds ratio of 1.45. The paper does not explain why these reported analyses differ.
Declared interests
The investigators reported no financial or nonfinancial disclosures.
The easy way to misread this
Do not conclude that rehabilitation services caused employment or that a specific therapy was effective. This was a cross-sectional survey, and it did not record the type, content, duration, or provider of the services, so no single component can be credited.
