Because the type and age of patients treated may vary from program to program, the comparison of cycle statistics is complex. Couples should be aware of differences among programs as well as differences in specific characteristics when reviewing the data. There are a number of factors to keep in mind when reviewing data.
Comparison of programs is complicated. Only annual data should be quoted since short-term trends are unreliable. Outcomes should be reported clearly in terms of live births per cycle (clinical pregnancies for the latest year), retrieval or transfer. Success rates reported in the SART Data Registry format cannot be compared to programs that do not report to SART since non-reporters may utilize formats designed to inflate their success rates.
The following are our results as reported to the SART/CDC reporting system. In order to get a long-term view of our results we are presenting a cumulative report of the last five years as well as 2010, the latest reporting year (expressed in clinical pregnancies since not all the births have occurred and been reported). As entry criteria are highly variable for each program, and treatment processes vary, a center-by-center comparison of results may not be meaningful.
