Results for Cox proportional hazards models of risk of nest and brood failure.

Table 4. Coefficient estimates (β), precision (SE), significance (P), and estimated hazard ratios and corresponding confidence limits (CL) for the Cox proportional hazards model of risk of nest and brood failure among sage-grouse that occupy a human-modified landscape in the Intermountain West, USA.
aHazard ratio calculated based on a unit of 1 m, 0.1 units, and 1 m for SD of slope, CV of elevation, and mean distance to mesic habitat, respectively.
