Results Between 2009 and 2018, the annual age‐standardised incidence rates of CLL/SLL (range, 600.05–887.92 cases per 10 7 person‐years) and WM (range, 41.48–78.19 cases per 10 7 person‐years) showed an increasing trend (coefficient: 26.98 [ p = 0.023] and 3.20 [ p = 0.009], respectively).
However, it was reassuring that a clear trend was shown for all rates in both conditions with high R 2 (i.e., > 0.80 for the prevalence proportion by age group model), suggesting that the model was a good fit.
Recent studies using registry data indicated a decreasing trend in the incidence‐based mortality of CLL in Switzerland [ 2 ] and WM in women in the US [ 13 ].
