    controlled trial to examine the effect of enhanced reminders on
    the socioeconomic gradient in uptake in bowel cancer screening’,

    randomised trial of strategies to increase cervical screening
    uptake at first invitation (STRATEGIC)’, Health Technology
    Assessment, 2016. It’s worth noting that despite their widespread
    use, the concept of randomised experiments (often called ‘A/B
    tests’) seems to make many people uncomfortable – even if the
    individual options are innocuous and the study is ethically
    designed. One 2019 study found that ‘people frequently rate A/B
    tests designed to establish the comparative effectiveness of two
    policies or treatments as inappropriate even when universally
    implementing either A or B, untested, is seen as appropriate’.
