Both groups in this study used smoking cessation products, and so it would have been helpful to know how much they cost, even if it was just a quick approximation or discussion of affordability. At the same time, these aren’t high-dollar items, so cost isn’t as important to discuss as say, when reporting findings about a new cancer drug or surgery. The story gives the absolute number of participants (697) who were enrolled in the trial and then reports the percentages of participants who stopped smoking. While it reported reduced cigarette consumption in relative numbers, it did specify that participants smoked at least 15 cigarettes a day, giving somewhat more meaning to these percentages (e.g. “decrease their smoking by an average of 29%”). It told us quit rates at four weeks and six months, too–so we get some sense of change over time on results. It also placed these results in the greater context of what we know about quit rates among smokers. When quitting, heavy smokers can experience withdrawal symptoms–such as depression, insomnia and decreased heart rate–even if they use nicotine replacement products. The article did refer to “withdrawal” and “urge intensities” and so we’ll considered that sufficient. However, the piece would have been stronger had it specifically discussed the withdrawal symptoms mentioned above. The story sufficiently discusses the quality of evidence here, including that participants were assigned to one of two treatment groups. We’re told how far out the the study lasted, too–an indirect measure of quality, since long-term success rates are important for addictive behaviors. We also liked this frank sentence: “The researchers acknowledge that this is hardly the last word on the best way to quit.” The story does not engage in disease mongering–a smoking habit is unhealthy and harmful, and efforts to improve quit rates are important to study. This story does not include any comments from independent sources–or even from one of the researchers themselves. It only refers to the original journal article. Why does this matter? It’s always a good idea to consult an outside source because it’s likely to yield insights and context that otherwise would be lacking. But overall, this is a case where the story is still fairly strong, regardless of the lack of sourcing or interviews. The study is comparing two alternatives when quitting smoking–either cold turkey or gradually. The story discusses these options, along with the use of nicotine replacement in both scenarios. That’s enough to qualify as Satisfactory. However, another alternative the author didn’t mention was medications that can help with cravings–such as bupropion. What does the research say (if anything) about how those medications might augment quitting? That’s important to discuss. The availability of cigarettes or smoking cessation products is not in question. Although the story uses the word “new” when it means “latest” in the lead paragraph, we feel it did a good enough job referring to other studies to merit a Satisfactory rating. Despite the lack of original comments, this LA Times article does not appear to be based on any news releases we found online.
