Figure 2 depicts a PRISMA chart for study retrieval and selection. To the left are three horizontal boxes (from the top down), Title & Abstract screening, Full text screening, and Included Studies. On the top are two boxes, Records Identified through database searching n = 10,505, and Reviewer nominated records n = 34. A dotted line from the right hand box line points to a box on the left, Duplicate records removed n = 3,783. Lines come down from the two top boxes to a box, Records eligible for level I screening n = 6,756. A dotted and wavy line from that box points to a box on the right, Records excluded at level I n = 5,417. A line goes down from the middle box (Records eligible for level I screening) to a box, Records eligible for level II screening n = 1,339. A wavy dotted line points right to a box, Full text not available n = 172. A solid line goes down from the middle box to a box, Full text articles assessed for eligibility n = 1,167. A dotted and wavy line goes right to a box, 811 Full text articles, excluded. - 334 Editorial, review, commentary, letter, news, report or case report - 17 Systematic reviews relevant to topic - 45 Non-comparative observational study that may have reported harms of CAM - 29 Comparative observational study not reporting on harms of CAM - 276 Not a CAM intervention or multimodal intervention - 43 Not a relevant population or cause of pain 42 Reported outcome for more than one region without stratification or irrelevant region - 7 Not an eligible language – - 18 Did not report outcome of interest. Another arrow points down from the middle box to a box, Studies included in the qualitative synthesis n = 356 (including 86 2(unclear superscript) publications) - RCTs reporting on efficacy, harms and/or economic evaluation n = 351 (265 primary trials) - Controlled observational studies reporting on harms; n = 5. Two arrows go down from that box to two below it. The box on the left, Low Back Pain (primary studies: n = 187* + 64 2 (unclear superscript) publications) Acupuncture: n = 105 Manual treatments: Manipulation (and flexion-distraction): n = 39 Mobilization: n = 18 Manipulation + mobilization: n = 10 Massage: n = 20 Economic: n = 7. The right hand box, Neck Pain (primary studies: n = 109* = 27 2 (superscript unclear) publications) Acupuncture: n = 52 Manual treatments: Manipulation: n = 29 Mobilization: n = 12 (+ 1 thoracic study) Manipulation + mobilization: n = 2 Massage: n = 15 Economic: n = 3. From those two boxes, two lines come down to converge on the bottom box, Studies included in quantitative analyses n = 33.
