Dummy pre-post UCO (pre-time)
|
Captures the (vertical) shift of mean IBI values, induced by the interrupted treatment (UCO)
|
Group*pre-post dummy
|
Captures the differential shift of mean IBI length values immediately after UCO - significant only for the HI group
|
Pre-UCO time
|
Captures a linear increase of mean IBI length over time before UCO Note: Non-significant
|
Post-UCO time
|
All 3 time associated parameters capture curve-linear changes of mean IBI lengths over time after UCO
|
Post-UCO time (2)
|
Post-UCO time (3)
|
Residual variance
|
Captures within subjects variability (noise)
|
Random intercept variance, pre-UCO time
|
Captures between subject variability at the outset
|
Random slope variance, pre-UCO time
|
Captures between subject variability with respect to linear IBI changes over time before UCO (each animal has its own slope)
|
Random slope variance, post-UCO time HI
|
Captures heterogeneity of between subject variability with respect to linear IBI changes over time after UCO; larger variable responsiveness for the HI group
