| Analyte | Controls | CRPS | P |
|---|---|---|---|
| (n = 60) | (n = 160) | ||
| GABR | 0.727 ± 0.037 | 0.437 ± 0.018 | 1.0 × 10−09 |
| L-Kyn/L-Trp | 0.043 ± 0.001 | 0.050 ± 0.001 | 0.00097 |
| Neopterin (nM) | 5.97 ± 0.22 | 6.76 ± 0.20 | 0.01245 |

This table lists the global arginine bioavailability ratio (GABR) (defined as plasma L-arginine/(L-ornithine + L-citrulline), the plasma L-kynurenine to L-tryptophan ratio, and the plasma levels of neopterin and cortisol in CRPS and healthy control subjects. Values are given as the mean ± the standard error of the mean. Significant difference between the control and CRPS groups was determined with the Student's t-test. Statistically significant probability values (P < 0.05) are highlighted in bold.
