Comparison of platelet indices and percent change in platelet indices between groups
| Platelet indices | Group 1a (n=50) | Group 2b (n=50) | Control group (n=50) | P-value |
|---|---|---|---|---|
| AMPV (fL), mean ± SD | 8.8±1.3 | 8.7±1 | 8.0±1.1 | 0.002 |
| APDW (fL), mean ± SD | 12.8±1.4 | 12.6±1.4 | 11.5±1.9 | <0.001 |
| MPV2 (fL), mean ± SD | 9.28±1.6 | 10±1.6 | 8±1.1 | <0.001 |
| PDW2 (fL), mean ± SD | 13.3±1.6 | 14.1±1.8 | 11.5±1.9 | <0.001 |
| Δ%MPV, median (IQR) | 2.2 (−1.1 to 7.5) | 14 (5.5 to 24) | 0 (−2.5 to 2.8) | <0.001 |
| Δ%PDW, median (IQR) | 2.9 (−0.7 to 8.3) | 12.5 (2.8 to 19.5) | 0.7 (−1.2 to 1.3) | <0.001 |
