Point biserial correlations (rpb) between low and high participation in skin-to-skin care (SSC) and Bayley-III cognitive and communication outcomes
| Bayley-III assessment | SSC low* | SSC High* | rpb | p Value† |
|---|---|---|---|---|
| Cognitive 6 months | 92.7 (15.7) | 96.3 (15.1) | 0.11 | 0.30 |
| Cognitive 12 months | 93.1 (14.6) | 93.9 (19.2) | 0.03 | 0.82 |
| Communication 6 months | 93.1 (12.9) | 96.9 (16.6) | 0.13 | 0.24 |
| Communication 12 months | 90.7 (15.4) | 98.2 (16.4) | 0.23 | 0.05 |
| Composite (cog/comm) 6 months | 92.9 (12.6) | 96.6 (14.4) | 0.13 | 0.21 |
| Composite (cog/comm) 12 months | 91.9 (13.6) | 96.1 (16.1) | 0.14 | 0.22 |
*Numbers in each cell are mean (SD).
†p Values are from test that point biserial correlations are different from zero.
