This corrects the article "Premonitory Symptoms in Migraine: Implications for Disease Burden and Cognitive Impairment, with Some Promising Answers " on page 130.
This is a correction to an already published paper (Headache Pain Res 2025;26(2):130-141; https://doi.org/10.62087/hpr.2024.0031). We found errors in the IQR values in Tables 1 and 3. Appropriately adjusted are as below.
This error does not change the text and the conclusions of our paper. We apologize for the unintentional mistake and appreciate the opportunity to correct and clarify the issue.
Table 1.
Comparison of demographic features between the PS+ and PS– groups
Parameter PS+ (n=139) PS– (n=47) p-value†
Mean age (yr) 35.1±10.4 36.9±11.3 0.397
Female sex 117 (84.2) 42 (89.4) 0.477
Chronic migraine 28 (20.1) 10 (21.3) 0.837
Migraine with aura 51 (36.7) 8 (17.0) 0.017*
MMD (IQR) 5 (3–10) 6 (3–10) 0.889
VAS (IQR) 8 (7–9) 8 (7–10) 0.498
Oral preventatives: small molecule 73 (52.5) 16 (34.0) 0.042*
Onabotulinumtoxin-A 18 (12.9) 1 (2.1) 0.048*
GON blockage 27 (19.4) 11 (23.4) 0.677

Values are presented as mean±standard deviation, number (%), or median (IQR).

PS+, premonitory symptom positive; PS–, premonitory symptom negative; MMD, monthly migraine days; IQR, interquartile range; VAS, visual analogue score; GON, greater occipital nerve.

*Asterisk indicates a statistically significant (p<0.05). †For parameters given as either mean±standard deviation or median (IQR), the Mann-Whitney U-test was used to obtain p-values. For parameters given as frequency, the chi-square test was used to obtain p-values.

Table 3.
Comparison of the PS+ and PS– groups in terms of migraine trigger factors
PS+ (n=139) PS– (n=47) p-value†
MIDAS (IQR) 26 (14–40) 16 (10–33.5) 0.05
Mig-SCOG (IQR) 10 (7–14) 7 (4–10) <0.001*
WHOQL-8  (IQR) 3.12 (2.75–3.62) 3.62 (3.12–4.00) <0.001*

Values are presented as or median (IQR).

PS+, premonitory symptom positive; PS–, premonitory symptom negative; MIDAS, Migraine Disability Assessment Scale; IQR, interquartile range; Mig-SCOG, Migraine Attack Related Subjective Cognitive Scale; EUROHIS-8, European Health Impact Scale.

*Asterisk indicates a statistically significant (p<0.05). †For parameters with IQR values, the significance between groups was tested with the Mann-Whitney U-test.
