Corrigendum to “Neuromelanin levels in individuals with substance use disorders: A systematic review and meta-analysis” Neurosci. Biobehav. Rev. 161 (2024) 105690 (Neuroscience and Biobehavioral Reviews (2024) 161, (S0149763424001593), (10.1016/j.neubiorev.2024.105690))

We regret an error in our article within the June issue of Neuroscience & Biobehavioral Reviews (Ahrens et al., 2024). We originally reported the values provided in Table 2 of Little et al., (2009) as standard deviation (SD) values. But based on the information now available to us, these are rightly considered to be standard error of the mean (SEM) values. With these values corrected, the following changes to the original results are made, including changes to Table 3 and Figures 2 and 3. However, we highlight the fact that no analyses became significant or unsignificant if they were not previously reported as such.
