Nancy Padian and colleagues (July 21, p 251) 1 found no protective effect against HIV infection of diaphragms plus lubricant gel “over and above that of condoms”. Specifically, they saw similar rates of infection in the intervention and control groups, with higher reported condom use at last sex in the control group (85% vs 54%). I am surprised, therefore, that Padian and colleagues did not report on that very point—the efficacy of condom use itself (if any) by those reporting use or no use of condoms within the study cohort. This point is important because an alternative interpretation of the results might be that diaphragms are “just as good” as condoms and thus the results could support the recommendation of diaphragms to prevent HIV. Assessment of the effectiveness of condoms is difficult since con dom use paradoxically often seems to be a marker of elevated risk. However, women recruited to the study were all at some significant risk and reported condom use was quite high. Moreover, Padian and colleagues seem to have collected rich information about condom use and various risk factors, which should offer the opportunity for some control of confounding variables and perhaps assessment of the degree of condom use.If condom effectiveness against HIV was high, such a finding might argue that diaphragms might also be protective. However if condoms were actually used rather haphazardly or reflect more the “normative” positive response, and were hence not very effective, it argues for lack of much effect for diaphragms as well. In view of the rather high rates of infection (4% per year), it might well be that neither condoms nor diaphragms were especially protective.
