High Frequency and Low Intensity Transcranial Magnetic Stimulation for Smoking Cessation

Figure 1

Changes in exhaled CO during the 8-week period of stimulation. There was a statistically significant difference in CO concentration in different time points: from baseline to week 3 ( < 0.01), week 5 ( < 0.01), week 6 ( < 0.01), and last week 7 ( < 0.01). CO, carbon monoxide; PPM, parts per million.
