This may be a data quality issue. The incidence of cord pH less than 7.00 recorded as 0 is probably a data quality issue. The incidence of caesarean section at VE =10 at 1.8% is a little low and may be a data quality issue as is admissions to the neonatal unit which has been lower this year. These comments are very similar to the Group 1 table and therefore more likely to be data quality issues.
