Table 4.
Subgroup analysis for age group 75 years and older: proportional annual change in predicted mean number of contacts with an out-of-hours PCS/1000 inhabitants, per year and neighbourhood SES stratum*; and unstandardised regression coefficients for difference-in-difference year (2016 vs 2013) and neighbourhood SES (very low vs very high)*
| Year* Neighbourhood SES | Total contacts | High-urgency contacts | Low-urgency contacts | Contacts during night time | Contacts evening, weekend, holidays | Home visits | Consultations | Telephone consultations |

PCS, primary care service; SES, socioeconomic status.
