|---|---|---|---|
| 2016 | 2017 | 2018 | |
| One measurement | 173,258 (100) [173,258] | 124,584 (72) [124,584] | 133,211 (77) [133,211] |
| 2–4 measurements | 30,085 (100) [66,528] | 20,171 (67) [44,258] | 21,261 (71) [46,544 ] |
| >4 measurements | 92 (100) [633] | 47 (51) [348] | 51 (55) [345] |
aThe index is shown using 2016 as baseline. Indexes show that the drop in measurement counts is more pronounced in patients with multiple measurements than in patients with a single measurement. Number of analyses are given in square brackets.
