Questions car safety statistics

I was disappointed at the editorial decision to publish the paper by Dr. Kanthr, "Car Safety for Infants: Effectiveness of Prenatal Counseling" (Pediatrics 58:320, September 1976). Dr. Kanthor himself must have realized that the differences between his counseled and noncounseled group in the proportion of children being adequately restrained in their family automobile at the six-week well-child visit did not reach statistical significance (df = 1, χ2 = 1.527, .2 < P < .3). He justifiably claimed that the results suggested only a trend, but he did claim that the differences observed in the two groups resulted from the single counseling session.
