Table 1. Calculation of palmaris longus agenesis association with handedness.
| Right handed | Left handed | |||
|---|---|---|---|---|
| Results | Expected | Results | Expected | |
| PL on R | 216 | 217.15 | 24 | 24.34 |
| PLA on R | 16 | 14.85 | 2 | 1.66 |
| PL on L | 167 | 165.6 | 28 | 28.08 |
| PLA on L | 10 | 11.33 | 2 | 1.92 |
Abbreviations: L, left; PL, palmaris longus; PLA, PL agenesis; R, right.
Note: Summary of actual and expected results of palmaris longus presence and agenesis based on handedness. There was no statistical significance to support right handedness being associated with agenesis. There was insufficient sample size to determine significance on the left.
