A study of the effect of exposure to color ( red or blue) on the ability to solve puzzles used 48 subjects. Half the subjects were asked to solve a series of puzzles while in a red-colored environment. The other half were asked to solve the same series of puzzles while in a blue-colored environment. The 24 subjects in the red-colored environment had a mean time for solving the puzzles of 9.65 seconds with standard deviation 3.47 ; the 24 subjects in the blue-colored environment had a mean time of 15.85 seconds with standard deviation 8.65 . The two-sample t statistic for comparing the population means has value ( ± ± 0.001)

What is the exposure? What is the outcome? Study information: Background The effect of tobacco smoking and alcohol drinking on esophageal cancer (EC) has never been explored in Spain where black tobacco and wine consumptions are quite prevalent. We estimated the independent effect of different alcoholic beverages and type of tobacco smoking on the risk of EC and its main histological cell type (squamous cell carcinoma) in a hospital-based study in a Mediterranean area of Spain. Methods We only included...
