Research by Shephard EA and Hamilton WT, Selection of men for investigation of possible testicular cancer in primary care: a large case–control study using electronic patient records. Br J Gen Pract 2018; DOI: https://doi.org/10.3399/bjgp18X697949 showed an inaccuracy in the print version. The printed version states ‘Testicular swelling alone has a PPV for cancer just below the 3% threshold, but when combined with testicular, groin or abdominal pain, particularly in men aged >50 years, the likelihood of cancer is considerably greater.’ The corrected version should read ‘A testicular lump alone has a PPV for cancer just below the 3% threshold, but when combined with testicular swelling, pain or abdominal pain in men <50 years, the likelihood of cancer is considerably greater.’ This appears in the grey box at top of print abridged version only. The online version is correct.
