Change in mean (95% CI) total ABC raw scores from baseline using sex- and fever response-matched pairs. Change in mean score was significantly different between the sulforaphane (SF) and placebo (PL) groups at 15 weeks. Both groups’ scores improved during the open label phase after 15 weeks (shaded box). Note: 95% CI not shown for week 36 due to small sample size; see Additional file 1: Table S8 for mean (SD). *p = 0.02
