It just passed and I didn't realise - it was on 21 October last year that David Tuller posted the first in his series of Trial by Error articles about PACE on Virology Blog. Since then, the landscape has transformed. Scientists, clinicians and statisticians, thousands of patients and dozens of patients' groups have been emboldened and inspired to speak out about PACE. Now the data have been released, the reanalyses are shocking, the walls are crumbling, and David Tuller keeps on writing... Thank you, David Tuller!
