- †Based on the odds ratios from the multivariable analysis. Replacement breeding cattle groups that were not significant in the multivariable analysis were assigned a score of 1.00.
- ‡Based on the odds ratios directly reported in the original within-herd simulation model analysis.
- *Calculated as the magnitude difference in betweenness centrality scores relative to the value for open heifers.
- An overall risk score was calculated for each replacement breeding cattle group by summing the relative risks predicted by each of the study analyses.
