Large multi-centre pilot randomized controlled trial testing a low-cost, tailored, self-help smoking cessation text message intervention for pregnant smokers (MiQuit).

Using this outcome, we found that 5.4% of women in the MiQuit group stopped smoking during pregnancy and 2.0% did in the control group, and this almost reached statistical significance; it is likely, when tested on a larger scale, that MiQuit will prove to be both effective and cost‐effective for promoting smoking cessation throughout pregnancy.
