The story does not mention the cost of the vitamin supplements. The story quantifies the number of cases of AMD in the vitamin group as well as the control group. The story should have provided a denominator for these numbers so that the reader can get a sense of the size of the risk. The story does not mention any harms of b-vitamin supplements. While they are generally safe, the FDA does not regulate supplements and therefore there is no guarantee of strength, purity or safety of products. Furthermore there are some important contraindications and consumers should talk with their doctor about before taking the vitamins. The story adequately describes the current study and discusses some of its strengthes and weaknesses. The story does a particularly good job of describing the study design, the sample size and duration of follow-up. The story does not exaggerate the seriousness or prevalence of AMD. The story should have explained that there are two types of AMD: dry and wet. Dry AMD is more common, progresses more slowly and may respond to vitamin supplementation, whereas wet AMD, although more rare, progresses rapidly and may not respond to vitamins. The story quotes an expert who is not related to the study or employed by the vitamin manufacturer. The story does a good job of describing potential conflicts of interest of the quoted experts. The story mentions smoking cessation and laser treatment as alternatives. The story however might have mentioned the other prevention methods listed on the National Eye Institute website: control of diet, exercise, weight, and blood pressure. Clearly vitamin-b supplements are available, however the story should have described whether this particular combination of vitamins is available and if so, if they are available over the counter or by prescription only. The story adequately represents the novelty of taking vitamins for AMD, which is not a new idea. Given the fact that an independent expert was interviewed, it's safe to assume it did not rely solely or largely on a news release.
