A series of sensitivity analyses to cope with missing data did not change the main results, except that 1) the marginally significant associations (including myopathy associated with statin use; dementia, TIA and BMI≥35 associated with high-intensity statin use) in the main analysis vanished but IMD groups 2 and 3 were associated with slightly decreased use of statins when the analysis was restricted to those with individual IMD; and that 2) the associations of BMI≥35 with increased use of any statin and high-intensity statin vanished when the missing value of BMI was replaced by the 95th percentile value.

The sentences
First, the general trend ran parallel to an increasing trend in statin use prior to stroke, which accounted for less than 10% of patients in 2000 and over 40% in 2014, and these prior users of statins continued to use them after stroke in almost 90% of cases throughout 2000–2014.
