| Groupa | N | Mean (mm2) | SD | Weighted meanb | Weighted SD |
|---|---|---|---|---|---|
| Control | 40 | 0.10 | 0.50 | 0.12 | 0.70 |
| NSAID | 40 | 2.74c | 2.99 | 3.25c | 4.43 |
| Probiotic | 39 | 1.91c | 3.12 | 2.43c | 5.00 |
aThe treatment groups were control, indomethacin-challenged group (NSAID), and a probiotic group supplemented daily with 1010 colony forming units of Bifidobacterium lactis 420 for seven days prior to indomethacin challenge.
bThe weighted values were calculated by multiplying the detected TDA values of increasing severity with 1/10, 3/10, and 6/10, respectively.
cANOVA P < 0.0001 when compared with control.
