↵a Shading: PPV 1–1.9% (yellow) and 2–2.9% (amber): NICE suggests GPs consider primary care testing.≥3% (red): NICE recommends referral for specialist review or definitive investigation if the investigation is available to the GP. The combined analysis includes: colorectal, gastro-oesophageal, lung, multiple myeloma, non-Hodgkin’s lymphoma, ovarian, pancreatic, prostate, and renal tract cancer. Prostate cancer is removed from the female analysis, and ovarian from the male. No shading: <1%, no testing needed. LR = likelihood ratio. NICE = National Institute for Health and Care Excellence. SR = systematic review.
