Unfortunately, methodology section seems to be faulty in this publication. Some of the information I did not find when reading it: 1. What was the administration scheme of naringin (once daily, weekly, other)? 2. What was the dose of cisplatin used (as unlikely as it seems to be, the authors really have forgotten to report it)? 3. Have the behavioral tests been done 48 or 24h prior to animal killing? Both contradictory information were given. I am afraid this paper is not really useful without clarification upon these issues, once they are critical for the methodology the researchers used. Maybe editorial and peer reviewing process could have been a little more rigorous in this case? I disclose no conflicts of interest.
