title: Validity of an assumption underlying the confirmed bleeding day measurement in an experimental clinical trial.
abstract: In a clinical trial involving gingival bleeding, one measurement proved far better than the others. It was assumed that this measurement would help to eliminate certain sources of error. This paper examines data from the trial which give support to the assumption.
