Regression results comparing the differences in the milk output between domperidone and metoclopramide before and after adjusting for baseline milk outputs

Domperidone>metoclopramideMean difference (95% CIs)p Value
Estimates adjusting for the day of output
Estimated difference before medication (n=65)41.5 (−17.9 to 100.8)0.171
Estimated difference during medication (n=65)75.2 (−0.1 to 150.3)0.05
Estimated difference after medication (n=50)*82.2 (−2.4 to 166.9)0.057
Adjusted differences (adjusted for the day of output and baseline milk output)
Estimated difference during medication (n=65)31.0 (−5.67 to 67.9)0.098
Estimated difference after medication (n=50)*15.3 (−40.1 to 70.6)0.589
  • * Although the difference after treatment appears to be higher, this is due to the fact that the women who collected postmedication data were those who were less likely to seek a further prescription, and therefore those with larger milk volumes. Once the baseline milk volumes had been taken into account, the true difference is much smaller.
