Crossover Studies with Continuous Variables
2011Crossover studies with continuous variables are routinely used in clinical drug research: for example, no less than 22% of the double-blind placebo-controlled hypertension trials in 1993 were accordingly designed (Niemeyer et al. 1998). A major advantage of the crossover design is that it eliminates between-subject variability of symptoms.

Crossover and Parallel Study of Oral Analgesics
The Journal of Clinical Pharmacology, 1981Abstract: Ten years ago, analgesics were studied using crossover designs. In recent years, analgesics have been studied only in parallel designs primarily because biostatisticians do not like crossover studies. The advantages of crossover studies are numerous: (1) patients serve as their own control; (2) there is less variability of responses among ...

Cephaloglycin: Crossover absorption studies and clinical evaluation
Clinical Pharmacology & Therapeutics, 1969Studies with volunteers on oral administration of cephaloglycin resulted in low serum but higher urinary concentrations. Although some absorption was observed with orally administered cephaloridine, serum levels were shorter in duration and urine concentrations were lower than those observed with cephaloglycin.

Sensory experiments as crossover studies
Food Quality and Preference, 1998Abstract In most sensory studies the products are evaluated one after another. There is concern that the perception of assessors might be influenced by carryover effects. Therefore it might be useful to use a design which is balanced for carryover effects and to not randomize the order in which the products are tasted.
