Characteristics of the participants
The participants’ characteristics are reported in Table 1 . Fifty-seven obstetricians answered the questionnaire: 40 had already participated in specific training in physiology-based CTG interpretation and were included in the training group, and 17 participants were included in the control group. The level of experience was the same in both groups (p = 0.623). The majority of participants were residents (in their fourth year or higher) and worked in a university hospital. Participants in the training group either participated in a two-day master class (27.5%), had a shorter training course (72.5%) or read a book on physiology-based CTG interpretation (25.0%). Most of the participants in the training group declared using this teaching in their daily practice (95.0%).
