Their previous systematic review [2], published in the BMJ, has been subject to substantial criticism by various authors and institutions [3–7]. Taylor-Robinson and colleagues have now responded to these criticisms by updating the original Cochrane review to include a number of recent trials and by giving more attention to two of the previous criticisms, i.e., outcome after longer follow-up and additional analysis taking worm intensity and prevalence into account.</p>
