The study has limitations mainly related to the data quality that cannot be excluded as possible
explanations of the findings. The validity of the analyses presented is crucially dependent on
the extent to which CS rates are representative of each country. [29-30] It is more likely that CS
rates were more imprecise in low-income countries than in middle- or high-income countries.
45% of the estimates are from DHS surveys, or needed to be adjusted from hospital rates, all of
them low-income countries. Therefore it is more likely that the needed number of CS is a much
more imprecise figure than the number of CS in excess, which is based on much more reliable
data.
