Preliminary Results for PFO Closure Trial
Depending which article you read, the MIST trial‘s preliminary results are great news or a terrible disappointment. Specifically, if you read the article in a health section, the results are positive; in the business section, they’re negative.
Looking beyond the spin, here are some of the more concrete preliminary findings:
- 37% of the patients whose PFOs were closed reported a reduction in the number and duration of their migraines. (It’s important to note that their migraines didn’t disappear completely, but were eased.)
- 17% of the control group participants, who had “sham” surgery, reported similar relief.
- Data suggest that the number of patients who benefited grew over time.
