Input: Seven trials met the inclusion criteria and had a total of 4526 women. Five were multi-site studies. Four trials were conducted in the USA, while Nigeria and Zambia were represented by one study each, and one trial was done in both Jamaica and India. Two trials provided multiple sessions for participants. In one study that examined contraceptive choice, women in the expanded program were more likely to choose sterilization (OR 4.26; 95% CI 2.46 to 7.37) or use a modern contraceptive method (OR 2.35; 95% CI 1.82 to 3.03), i.e., sterilization, pills, injectable, intrauterine device or barrier method. For the other study, the groups received educational interventions with differing format and intensity. Both groups reportedly had increases in contraceptive use, but they did not differ significantly by six months in consistent use of an effective contraceptive, i.e., sterilization, IUD, injectable, implant, and consistent use of oral contraceptives, diaphragm, or male condoms. Five trials provided one session and focused on testing educational material or media. In one study, knowledge gain favored a slide-and-sound presentation versus a physician's oral presentation (MD -19.00; 95% CI -27.52 to -10.48). In another trial, a table with contraceptive effectiveness categories led to more correct answers than a table based on pregnancy numbers [ORs were 2.42 (95% CI 1.43 to 4.12) and 2.19 (95% CI 1.21 to 3.97)] or a table with effectiveness categories and pregnancy numbers [ORs were 2.58 (95% CI 1.5 to 4.42) and 2.03 (95% CI 1.13 to 3.64)]. Still another trial provided structured counseling with a flipchart on contraceptive methods. The intervention and usual-care groups did not differ significantly in choice of contraceptive method (by effectiveness category) or in continuation of the chosen method at three months. Lastly, a study with couples used videos to communicate contraceptive information (control, motivational, contraceptive methods, and both motivational and methods videos). The analyses showed no significant difference between the groups in the types of contraceptives chosen. These trials varied greatly in the types of participants and interventions to communicate contraceptive effectiveness. Therefore, we cannot say overall what would help consumers choose an appropriate contraceptive method. For presenting pregnancy risk data, one trial showed that effectiveness categories were better than pregnancy numbers. In another trial, audiovisual aids worked better than the usual oral presentation. Strategies should be tested in clinical settings and measured for their effect on contraceptive choice. More detailed reporting of intervention content would help in interpreting results. Reports could also include whether the instruments used to assess knowledge or attitudes were tested for validity or reliability. Follow-up should be incorporated to assess retention of knowledge over time. The overall quality of evidence was considered to be low for this review, given that five of the seven studies provided low or very low quality evidence.
Output:

Through February 2013, we did computer searches for randomized trials of ways to inform people about how well family planning methods prevent pregnancy. We wrote to researchers to find other trials. The new program could be compared to the usual practice or to another program or means of informing people. We found seven trials with a total of 4526 women. Two had several sessions for participants. One of those looked at the choice of birth control method. Women in the test program more often chose to be sterilized or to use modern birth control than women with the usual counseling. In the other study, the groups had different sessions on family planning. Both groups increased their birth control use. However, the groups were similar at six months in using methods that work well to prevent pregnancy. Five trials had a single session for each group. In one, women learned more from a slide-and-sound format than from having a doctor talk to them. Another trial found that effectiveness categories were better than pregnancy numbers for comparing the methods. Still another study provided structured counseling using a flipchart on family planning methods. The groups were similar in choice of birth control and in numbers who still used their chosen method at three months. The last study used videos to inform couples about family planning. The groups were mostly similar in birth control use after the videos. But those who watched videos on motivation and on family planning did not choose pills or an injectable method as often as those who watched only the family planning video. The studies had different types of participants and programs. We cannot say overall what would help consumers choose their method of birth control. Ways to inform women about family planning options should be tested in clinics. Trials should look at the choice of birth control method, along with how much consumers remember later.
