Natural history group
The term natural history group refers to subjects in a drug trial that receive no treatment of any kind and whose illness is, as a consequence, left to run its "natural" course. The term stems from the natural history of an illness, which is the course and outcome of that illness in the absence of treatment.
==First usage==
In 1863, Austin Flint (1812–1886) in his report of the first-ever trial that directly compared the efficacy of a placebo treatment with that of an active treatment, spoke of "the natural history of (untreated ) disease".〔(Flint (1863), p.18. )〕
