Strengths and Limitations
For the first time, we evaluated the acceptability of protocols for
predicting the outcome of ectopic pregnancy in patients with PUL, which
has implications for the application of these protocols to practical
clinical work. We evaluated for the first time the accuracy of the M6
model in predicting ectopic pregnancy. However, the studies were
inconsistent in terms of the definition of EP, the definition of PUL and
how to present the results of data analysis, and the threshold of
protocols were not identical, which rmay esulted in heterogeneity
between studies.
