Is it a nonpartisan policy research and advocacy group?

According to a consumer group's analysis,

The panels of experts assembled by the Food and Drug Administration to advise it on whether to approve new drugs and medical devices are often biased in favor of recommending approval

The consumer group in question? The National Research Center for Women & Families. They claim

...media coverage and lobbying tend to reflect the views of corporations and organizations whose interpretation of "the facts" is influenced by their own financial interests.

Their mission:

to use scientific or medical research information to improve the quality of women's lives and the lives of family members. We focus our efforts on the programs and policies that we believe can most benefit from the research-based information that we can provide and the attention that we can generate.

As a research-based center, we provide information that is based on facts, not ideology or financial ties to the programs or products we analyze. In addition to the scientific expertise of our highly qualified staff, we rely on the expertise of unbiased, well-respected researchers from across the country.

I'm sure they believe they're unbiased. But Dr. Diana Zuckerman, the president who is cited in the WaPo piece, seems to prefer government solutions: she's opposed to Social Security privatization, and argues that for women to get silicone breast implants is not part of their "inalienable right to choose" (does that mean she's not pro-choice?). While I think implants are generally silly, these are the conclusions from the Institute of Medicine's (IOM) Information for Women about the Safety of Silicone Breast Implants:
"The IOM committee's review of research and medical studies shows a local, but not general, reaction to silicone breast implants."

• There is no evidence that silicone implants are responsible for any major diseases of the whole body. Women are exposed to silicone constantly in their daily lives.
• There is no plausible evidence of a novel autoimmune disease caused by implants.
• The committee found no increase in either primary or recurrent breast cancer in women with breast implants. Some studies even suggest lower rates of breast cancer in implanted women.
• There is no danger in breast-feeding; cows' milk and infant formulas have a far higher level of silicon, a silicone component, than mothers' milk. Breast milk is the best food for babies.
• The major problems with implants are local, but not life-threatening, complications. These include implant removal, ruptures, deflations, capsular contracture, infection, and pain.
• Many women will have secondary problems such as severe contracture, rupture, and implant removal.
• Implants do not last forever; risks accumulate over time, and many women should expect to have more than one implant.
• Some women with breast implants are indeed very ill. However, the committee can find no evidence that these women are sick because of their implants.
