Variation of skin parameters, after lesion induction with SLS, for the healthy group (median (Q1, Q3)).
| Deviation of Skin Parameters at Forearm |
Healthy Group (n = 33) |
||
|---|---|---|---|
| HK | H0 | p-Value | |
| TEWL SLS | −0.2931 (−0.510, −0.180) | 0.0878 (−0.0924, 0.243) | <0.001 |
| Hydration SLS | 0.0000 (−0.133, 0.106) | 0.0065 (−0.0889, 0.138) | 0.347 |
| Erythema SLS | −0.0287 (−0.0371, 0.0644) | 0.0144 (−0.0775, 0.135) | 0.825 |
Q1—first quartile; Q3—third quartile. Deviation (variable) = [(variable at t8) – (variable at t0)]/(variable at t0). HK—healthy skin with kefir intake; H0—healthy skin without kefir intake; TEWL—transepidermal water loss. SLS—sodium lauryl sulphate. Groups compared by Mann-Whitney U test, with p < 0.05 for statistical significance.
