Table 2.
Comparison and correlation (r) of blood glucose levels of gingival crevicular blood (GCB) with finger stick blood (FSB)and venous blood (VB).
| Group | Variable | Mean ± SD (mg/dl) | ‘p’ value and correlation (r) |
|---|---|---|---|
| Diabetic group | GCB | 156.07 ± 49.23 | |
| FSB | 166.61 ± 52.18 |
p < 0.005, HS r = 0.986 |
|
| VB | 156.12 ± 49.89 |
p > 0.005, NS r = 0.972 |
|
| Non-diabetic group | GCB | 90.80 ± 11.07 | |
| FSB | 101.35 ± 13.05 |
p < 0.005, HS r = 0.820 |
|
| VB | 93.41 ± 9.30 |
p > 0.005, NS r = 0.721 |
|
p < 0.005, significant; p > 0.005, not significant.
1 > r > −1, significant correlation; r = 0, no correlation.
