Dear Editor,

Recently, we read with great interest the meta-analysis which was reported by Tarashi et al.[1] and evaluated the studies included in their article. We detected some important viewpoints about the validity of extracted data. In reported data about Japoni's et al. study,[2] a serious blunder was seen in the frequency of drug resistance in Fars province-Iran. According to the tarashi et al report, a bias was seen which produce wrong results about the prevalence of imipenem resistance in hospitalized burn patients in Iran,[1] Either similar error was seen about the data of Akhavan-Tafti et al. study[3] in meropenem resistance.

Despite the authors declared that their search strategy limited to March 2006–May 2015, but 13 articles were ignored during this time, and either few references were related to later years (2016 and 2017). Missing this impressive number of articles reduce the search quality and so the results [Table 1].

Following the mentioned lack of evidence, the authors declared that the included articles in their meta-analysis were limited to isolates collected from burn patients, but Jazani's et al. study,[4] was carried out on Pseudomonas aeruginosa isolates were collected from other clinical specimens.

Finally, the authors should perform sensitivity analysis excluding studies with a high risk of bias to explore the influence of biased studies. Moreover, the authors did not assess the quality of studies. Therefore, it is concluded that, the current meta-analysis producing incorrect results due to inappropriate search and in the following mistake reports.
