The autors state : "We did not find (...) that the effect of Lactobacillus on diarrhea duration was modified by (...) live versus killed Lactobacillus preparation". From this I infer that the authors suppose that killed Lactobacillus- bacteria are or can be as effective as live Lactobacillus-bacteria. Yet, in Table 1 (Included Studies)I see only 1 study having used killed L. acidophilus (Simakachorn et al.) Furthermore, is it methodologically correct to include in a meta-analysis such differents products? Killed bacteria are not live bacteria, I would say. Seems a bit strange to me. And how can one then conclude, on the basis of only 1 study, that killed bacteria could be effective in reducing the duration of diarrhea in children? |
