Sran M M. To treat or not to treat: new evidence for the effectiveness of manual therapy (Br J Sports Med 2004;38:521–5).

The volume number for reference 23 (Sran et al) was incorrectly published as 24; the correct volume number is 29.

In Table 2 the results for Giles and Muller should read: Greater short term benefit for back pain with manipulation, but not for neck pain. Acupuncture more effective for neck pain.

In the section “Definitions and search strategy” the first line of paragraph 2 should read: I searched Medline, Cinahl, and Embase databases for randomised clinical trials comparing manual therapy, including spinal joint mobilisation (with or without manipulation) or manipulation only with other conservative treatments for back or neck pain.
