“…While the authors conducted a systematic search, assessed the strength of the evidence, and included data in evidence tables, they did not report effect sizes or perform a meta-analysis, making it difficult to judge and compare the effectiveness of the interventions. Other systematic reviews are more limited in scope, focusing on (a) specific countries (e.g., Bambra, Whithead, & Hamilton, 2004;Clayton et al, 2011); (b) single aspects of disability/illness, such as autism (e.g., Westbrook et al, 2012), mental illness (e.g., Crowther, Marshall, Bond, & Huxley, 2001;Underwood, Thomas, Williams, & Thieba, 2006), multiple sclerosis (e.g., Khan, Ng, & Turner-Stokes, 2009), traumatic brain injury (e.g., Graham & West, 2012), low back pain (e.g., Tveito, Hysing, & Eriksen, 2004) or spinal cord injury (e.g., Lidal, Huynh, & BieringSørensen, 2007); or (c) particular intervention types, such as interventions based on an empowerment perspective (e.g., Varekamp, Verbeek, & Dijk, 2006), workplace disability management programmes (e.g., Gensby et al, 2012) or workplace-based return-to-work interventions (e.g., Franche et al, 2005). Some of these reviews use meta-analytic synthesis methods, but several are quite dated and none explicitly focus on programmes conducted in LMICs.…”
