Subgroup analysis of mydriasis versus non-mydriasis in telemedicine detection of absence of DR and mild NPDR
| Absence of DR | Mild NPDR | |||
|---|---|---|---|---|
| Non-mydriasis | Mydriasis | Non-mydriasis | Mydriasis | |
| Se (95% CI) | 80% (75% to 84%) | 91% (89% to 94%) | 70% (65% to 75%) | 74% (67% to 80%) |
| Sp (95% CI) | 95% (93% to 96%) | 95% (94% to 96%) | 87% (85% to 89%) | 96% (94% to 98%) |
| PLR (95% CI) | 15.96 (7.90 to 32.25) | 17.70 (11.82 to 26.50) | 5.91 (3.58 to 9.74) | 20.94 (12.19 to 35.96) |
| NLR (95% CI) | 0.21 (0.14 to 0.32) | 0.09 (0.04 to 0.22) | 0.32 (0.21 to 0.50) | 0.27 (0.21 to 0.34) |
| DOR (95% CI) | 110.11 (37.04 to 327.31) | 254.95 (99.37 to 654.11) | 19.70 (8.63 to 44.96) | 42.52 (22.15 to 81.64) |
DOR, diagnostic OR; DR, diabetic retinopathy; NLR, negative likelihood ratio; NPDR, non-proliferative diabetic retinopathy; PLR, positive likelihood ratio; Se, sensitivity; Sp, specificity.
