In the original publication of the article, under the section “Clinicopathological characteristics”, the thresholds used for NLR was published incorrectly as 2.5. The correct value is 5.5.

The correct sentence should read as follows, “These derivative measurements were dichotomised into low and high groups by 5.5 for NLR, and 150 for PLR [6]”.
