Table 3.
The probability that a patient would be prescribed an ESR-AR or a COMP versus an ESR-NA device.
| Probability of being prescribed an ESR-AR over an ESR-NA | ||

| Days from injury to amputation = less than 12 days | 0.30 | 0.196 |
| Days from injury to amputation = at least 12 days | 0.70 | |
| Amputation etiology = cancer | >0.99 | <0.001 |

Values in bold indicate significant probabilities. ESR-NA, energy-storage-and-return and non-articulating; ESR-AR, energy-storage-and-return and articulating; COMP, computer-controlled.
