Table 3 Progression to KA depending on baseline rK39 sero-status. Hazard ratios and p-values estimated from fitted Cox proportional hazards regression models
From: Quantification of the natural history of visceral leishmaniasis and consequences for control
Baseline sero-status | Total evaluated | Progressors (%) | Hazard ratio (95Â % CI) | p |
|---|---|---|---|---|
Seronegative, rK39 ELISA < 20CU | 1,283 | 28 (2 %) | Ref. | N/A |
Seropositive, 20CU ≤ rK39 ELISA < 61CU | 204 | 7 (3 %) | 1.61 (0.71–3.70) | 0.26 |
Strongly seropositive, rK39 ELISA ≥ 61CU | 28 | 8 (29 %) | 17.7 (8.05–38.8) | 8.4 × 10−13 |
