An element of mystery in zinc cold treatments
Our Review Summary
The common cold is just that, common, and there is currently no cure. Treatments focus on reducing symptoms, but do not change the course of the infection. Prevention efforts focus on hand hygiene to reduce transmission. Large doses of vitamin C, echinacea and, more recently, zinc, have become increasingly popular judged by the number and variety of products that are now available. However, there is little evidence to support their use. This story reports on a recent review of the available literature on the evidence that zinc improves the outcomes in individuals with colds. The story does an excellent job of laying out the problem, describing the new information available from the literature review, and putting it into context for the reader.
The story does a good job of describing how many studies showed no effect of the zinc products. In the one study showing a benefit of zinc nasal gel, the story provides quantification of benefits in natural frequencies (days of duration of the cold) rather than in terms of relative reduction.
The story does a great job of describing the design of the current study, which is a special kind of literature review and quotes an independent expert as well as the lead author on the current study and the representative of the manufacturer.
Overall, this was a very well-written story, free of hype and full of helpful information.

Satisfactory
The story does a great job of describing the design of the current study, which is a special kind of literature review.
Satisfactory
The story does not exaggerate the seriousness or prevalence of colds. In fact the writer could have emphasized that colds are expensive, resulting in lost productivity and sick days due to illness in workers and their children.
Satisfactory
The story quotes an independent expert as well as the lead author on the current study and the representative of the manufacturer.
Satisfactory
The story mentions over-the-counter antihistamines, decongestants, and pain releivers as alternatives, appropriately pointing out that there is no "cure" for the common cold.
Satisfactory
The story clearly states that zinc products are available over the counter in drugstores.
Satisfactory
The story clearly states that zinc products are not a new idea.
Satisfactory
Because the story quotes multiple experts, the reader can assume that the story does not rely on a press release as the sole source of information.
