Post-training results interpretation assessment
| N | Image | Pr result | Cr result | Interpretation | Total responses | Correct interpretation, n (%) | Incorrect interpretations, n (%) | Correct interpretation of user-assigned PrCr values*, n (%) |

| 2 |  | 4+ | 4+ | Proteinuria | 88 | 84 (95.5%) | Normal: 1 (1.1%) Invalid: 3 (3.4%) | 85 (96.6)% |
| 3 |  | 2+ | 2+ | Proteinuria | 87 | 64 (73.6%) | Normal: 21 (24.1%) Invalid: 2 (2.3%) | 83 (95.4)% |

Variable print quality may have influenced accuracy of user interpretation against correct response.
*Excludes entirely blank responses (ie, participants did not provide an answer to question about results interpretation).
PrCr, protein-to-creatinine.
