Limitations and Caveats
| Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data |
|---|
| Instead of the intended endpoint 'heat pain and cooling threshold', results of 'summated 3 score for small nerve fiber function' were reported. |
