| Abuse unidentified to no abuse (B) | 0.025 | Lognormal (0.75) | Assumption |
| No abuse to no abuse (C) | 0.9867 | Complementary to A + K | |
| Control: abuse unidentified to identified existing victim (D) | 0.0094 | Lognormal (0.1) | From IRIS |
| Intervention: abuse unidentified to identified existing victim (D) | 0.0207 | Lognormal (0.1) | From IRIS |
| Control: abuse unidentified to advocacy (E) | 0.0016 | Lognormal (0.1) | From IRIS |
| Intervention: abuse unidentified to advocacy (E) | 0.0101 | Lognormal (0.1) | From IRIS |
| Control: abuse unidentified to abuse unidentified (F) | 0.9581 | Complementary to D + E + L | |
| Intervention: abuse unidentified to abuse unidentified (F) | 0.9383 | Complementary to D + E + L | |
| Advocacy to no abuse (G) | 0.0888 | Lognormal (0.75) | Ramsay et al19 intervention arm reduced by 75% to reflect lower ntervention intensity in IRIS |
| Advocacy to advocacy (H) | 0.9053 | Lognormal (0.75) | Complementary to G + L |
| identified existing victim to no abuse (I) | 0.0717 | Lognormal (0.75) | Ramsay et al19 control arm reduced by 75% to reflect lower intervention intensity in IRIS |
| identified existing victim to identified existing victim (J) | 0.9223 | Complementary to I + L | |
| Death rate if not being abused (K) | 0.0058 | Lognormal (0.75) | All-cause mortality22 |
| Death rate if being abused (L) | 0.0059 | Lognormal (0.75) | All-cause mortality22 + Walby23 |
↵* SDs are listed for the lognormal distributions and standard variances for the β distributions. The SDs used in the model were found by multiplying these numbers by the listed values (eg, the SD for transition rate A = 0.0075×0.75=0.0056).
