Distribution of NR as a percentage of WGA and overall probe findings (mean) in a lid across three groups
| Group | #WGA (sum) | #NR (within WGA) (sum) | %NR (within WGA) (mean) | %FFFUR | %SFT | %NR | Total glands |
| Group 1 (0 WGA) | 0 | 0 | NA | 61.9* | 24.4 | 13.7† | 334 |
| Group 2 (1–4 WGA) | 23 | 0 | 0% | 82.1 | 16.2 | 1.7 | 390 |
| Group 3 (>5 WGA) | 116 | 12 (range: 0–5) | 9.4%‡ (range: 0%–38.5%) | 77.1 | 17.1 | 5.8 | 272 |
| Total (38) | 139 | 12 | 996 |
*Significantly lower compared with group 2 (p=0.005) as per Mann-Whitney U test.
†Significantly higher compared with group 2 (p=0.011) as per Mann-Whitney U test.
‡Significantly higher compared with group 2 (p=0.005) as per Mann-Whitney U test.
FFFUR, firm, fixed, focal and unyielding resistance; NA, not applicable; NR, no resistance; SFT, soft resistance; WGA, whole gland atrophy.
