Association of coronary artery status with individual variables
| Criterion | CAA+ (n=95) | CAA− (n=417) | P values |
| Male | 62 (69%) | 247 (59%) | 0.27, NS |
| Median lowest albumin, g/L | 26 | 31 | 0.049 |
| Range | (13–41) n=83 | (21–49) n=372 | |
| Median lowest sodium, mmol/L | 134 | 134 | 0.92, NS |
| Range | (125–142) n=48 | (123–141) n=210 | |
| Median lowest platelet count, ×109/L | 212 | 245 | 0.15, NS |
| Range | (30–442) n=95 | (54–450) n=415 | |
| Median age months at presentation | 21.6 | 36.0 | 0.005 |
| Range | (2.4–190.0) n=93 | (1.2–190.0) n=409 | |
| Median time to treatment (days) | 10.0 | 7.0 | 0.005 |
| Range | (2–37) | (1–36) | |
| Mucosal involvement at diagnosis | 77/95 (81%) | 360/416 (87%) | 0.19, NS |
| December–May presentation | 64/95 (67%) | 245/416 (59%) | 0.12, NS |
| Presentation before 1 February 2014 | 53/95 (56%) | 210/416 (50%) | 0.35, NS |
| Primary steroid use | 11/95 (12%) | 13 (3%) | |
| Late corticosteroid use | 13 (14%) | 12 (3%) | |
| No corticosteroid use | 67/92 (73%) | 359/384 (93%) | 0.03 |
P value is the difference in median: NS. The numbers of patients receiving corticosteroids were too small for meaningful statistical testing. There were 11 children in whom the weights and z scores were missing and so have not been included in the table.
CAA+, those with coronary artery aneurysms; CAA−, those without aneurysms.
