Correction

In the article entitled "Scottish Intracranial Vascular Malformation Study (SIVMS): Evaluation of Methods, ICD-10 Coding, and Potential Sources of Bias in a Prospective, Population-Based Cohort" by Al-Shahi et al,¹ a reference to information in Figure 4 was printed incorrectly. The paragraph from page 1160 including the corrected text (in bold) appears below:

Sensitivity

The search of coding identified 58 (63%) of the 92 incident adults (Figures 2 and 4). Of these 58 adults, coding contributed only 4 who were unknown to SIVMS because collaborators failed to notify us of them (C in Figure 4). To evaluate sensitivity, ISD used probability matching record linkage to detect records of any hospital admissions and/or death certificates of all 92 adults. Of the 34 adults missed by the search of coding, 11 would never have been detected because they had not died and were never hospital inpatients (D in Figure 4). This makes the true-positive denominator for the calculation of coding sensitivity 81 (A–D in Figure 4), resulting in a sensitivity of 72% (95% CI, 61% to 80%). Coding missed the false-negatives (E in Figure 4) because of the incorrect allocation of Q27.3 to 8 adults and I67.1 to 3 adults (Table 1); the remainder were due to brain AVM diagnoses not appearing on the discharge summary or death certificate or missing records in the ISD data set.

The publisher apologizes for the error.
