Weinstein, Inc. are determined to not give up on their campaign against people protecting themselves from HIV. This is their latest poster:
What they're doing here is insidious, and evidence of how one can mislead with statistics without outright lying. The cover-your-ass statement here is "overall": the stats they're using to make their bar graph take into account all people in the studies, including the 53% of participants in the iPrEx OLE study who took less than 2 tablets per week.
However, what that indicates is that people in a study are bad at staying on a regimen, not the efficacy of the drug itself, which is over 99% effective at preventing HIV transmissions when taken 4 or more times per week.
The AHF may take the position that "the scientific data do not support the large-scale use of Truvada," just as some people take the position that scientific data do not support the idea of global climate change or that mankind would be contributing to it if it existed, but they're still wrong. Besides, low adherence is not a reason to condemn an effective drug as it is the responsibility of people using a tool to use it properly. Plus, if they really want to get nit-picky about adherence, then they might first want to focus on the rather abysmal usage rates of condoms, the only means of prevention they do support.
The problem with adherence is solved through education, not fear-mongering. It's almost like Weinstein and the AHF want people to continue contracting HIV...
