Average trajectories of responsive behaviours related to dementia for the 7 classes. Class 1: N = 11,601 – 69% of sample, lowest frequency/intensity; slightly increasing behaviours; class 2: N = 2220 – 13% of the sample, moderate frequency/intensity; slightly decreasing behaviours; class 3: n = 917; 5% of the sample, high frequency/intensity; decreasing behaviours; class 4: N = 916; 5% of the sample, low frequency/intensity; increasing followed by declining behaviours; class 5: N = 485; 3% of the sample, low frequency/intensity; rapidly increasing behaviours; class 6: N = 360; 2% of the sample, highest frequency/intensity; no change in behaviours; class 7: N = 301; 2% of the sample, low frequency/intensity; rapidly increasing followed by rapidly declining behaviours
