Study	Reason for exclusion
Gelbaya 2006	Retrospective non‐randomised controlled study.
Goldstein 1998	Study design and whether randomisation has been performed is unclear. It appears that patients serve as there own control after surgical intervention. Correspondance was sought to resolve this issue, but not with success.
Hotineanu 2007	This trial was excluded because this article compared proximal/distal tubal occlusion with clamping; however comparisons were between outcomes in different degrees of tubal pathology rather than different interventions. Comparative data was not obtained as correspondence was unsuccessful.
Mardesic 1999	This trial is not a randomised trial ‐ the 'control' group was historical (the same women prior to their salpingectomy) and biased by the fact that no pregnancies occurred.
Zolghadri 2006	The primary outcome of this study is the continuation of spontaneous pregnancy; IVF is not performed after tubal surgery.
