Strengths and Limitations
The main limitation of our study is that it is a retrospective study, articulated in 24 years, in which the standards of care, the characteristics of the women and the protocols have obviously changed, therefore the decision to perform a caesarean section in group 2A 4A may have been different in 2000 or 2019. Moreover, neonatal ICU is not available, so that group 10 mainly included women after the 34 weeks of gestational age.
However, these can also be considered the major strength, in the sense that the changes that have taken place over the years have been counterbalanced by the uniformity of behaviour, in the same institution.
