| Watersources | Mean ± S.D. | Mean ± S.D. of doxycycline concentrations (mg/l) | |||
|---|---|---|---|---|---|
| p value | After 1 h | After 3 h | After 5 h | After 8 h | |
| Tap water | Mean ± S.D. | 294.3 ± 0.81 | 271.1 ± 1.41 | 232.8 ± 1.66 | 207.5 ± 1.78 |
| p-value | 0.047* | 0.035* | 0.034* | 0.033* | |
| Ground water | Mean ± S.D. | 293.5 ± 0.74 | 248.5 ± 1.36 | 214.2 ± 1.76 | 179.7 ± 1.98 |
| p-value | 0.005* | 0.000* | 0.001* | 0.001* | |
| Control (therapeutic dose) | Mean ± S.D. | 300 ± 0 | 300 ± 0 | 300 ± 0 | 300 ± 0 |
