Interpreting confidence intervals around between-group differences. In the top half of the figure, the confidence intervals are narrow. Narrow confidence intervals are informative; they enable definite statements about the estimate of the treatment effect. In the bottom half of the figure, the confidence intervals are wide. Wide confidence intervals are less informative; they do not allow definite statements about the estimate of the treatment effect.
