Note characteristics according to patient level-corpus character thresholds

Character threshold	Number of unique notes included	Time delay between note and CTP scan time (minutes)	Word count	Character count
500	2 [1,2]	29.8 [15.6–92.9]	138 [67–481]	841 [488]
1000	2 [1–3]	31.3 [16.1–112.9]	212 [67–591]	1584 [173]
5000	3 [2–4]	42.4 [21.9–165.5]	464 [67–1098]	3187 [935]

Note: All figures are reported as median [IQR] and correspond to all patient notes that were added to patient-level corpora until minimum character threshold was reached.
