Convenient age cut‐offs for comparison of median CSF γδ T cell frequency in NIND, OMS and OIND*
| NIND | OMS | OIND | ||||
|---|---|---|---|---|---|---|
| Age range (years) | n | % (IQR) | n | % (IQR) | n | % (IQR) |
| 0–1 | 7 | 27 (23, 31) | – | – | 2 | (8·3, 8·5) |
| 1–2 | 11 | 12 (7·7, 23) | 78 | 9·9 (7·1, 15) | – | |
| 2–3 | 7 | 9·6 (8·0, 13) | 90 | 9·9 (6·4, 13) | 2 | (8·9, 6·7) |
| 3–5 | 14 | 9·0 (4·7, 11) | 79 | 9·4 (5·2, 14) | 5 | 7·9 (3·8, 12) |
| 5–10 | 21 | 7·3 (4·5, 10) | 40 | 6·0 (3·4, 8·6) | 8 | 4·8 (1·8, 9·2) |
| 10–15 | 31 | 5·0 (2·4, 6·9) | 11 | 4·0 (2·1, 8·1) | 3 | 4·7 (2·4, 7·5) |

*Expressed as percentage of total events. Age cut‐offs provide quasi ‘reference ranges’. Total n was 100 for NIND, 312 for OMS and 23 for OIND. For comparison, corresponding means ± standard deviation (s.d.) for OMS (top to bottom) were 11·9 ± 6·9, 11·5 ± 6·4, 10·6 ± 6·6, 6·5 ± 6·6, 5·3 ± 4·1, and 4·8 ± 4·6. For OIND (top to bottom from 3–5‐year range, they were 0·3). NIND = non‐inflammatory neurological disorders; OMS = opsoclonus–myoclonus syndrome; OIND = other inflammatory neurological disorders; IQR = interquartile range; CSF = cerebrospinal fluid.
