To the Editor: McVey and colleagues (1) conclude that a geriatric consultation team did not alter the degree of functional decline in elderly hospitalized patients. This negative conclusion may not be justified. Applying their criteria for functional improvement, they note that 34% of the patients in the intervention group improved, compared with 26% in the control group. They acknowledge the trend towards significance based on the confidence intervals, but state that it was a negative study because the results were not statistically significant. Others (2, 3) have shown the importance of looking at confidence intervals before labeling an intervention group
