Friday Fax: ANALYSIS: Critics' Attacks on Abortion/Mental Health Study Baseless: Disparaging comments on the methodology apparently resulted from the failure to read Dr Coleman’s section on it. Critics also ignored the data supplement with details on the selected studies. Dr Coleman’s methodology is sound, the selection criteria are clearly specified, and her strategy is in line with the generally accepted guidelines for meta-analysis.
One point of valid criticism recognized by Dr. Coleman is the heterogeneity of the underlying studies. In response, a follow-up meta-analysis was conducted by Professor David Fergusson of the University of Otago, Christchurch, that was limited only to studies that used an unwanted/unintended pregnancy comparison group. In this study (which is under review), the increased risk of developing mental health problems is lower than in Coleman’s, which uses several control groups. However, the results are the same: unswerving evidence that abortion is associated with an increased risk of mental health problems.
