Adjusting the black/white levels in an image can reveal inconsistencies barely perceptible to the naked eye.
A 2018 article in Scientific Reports was just retracted as a result of several such inconsistencies.

A 2019 Cochrane systematic review on using lithium to treat acute mania confuses standard error (SE) with standard deviation (SD) for two studies included in a meta-analysis, resulting in an overestimation of overall effect size in that meta-analysis.

"Data leakage" occurs when a statistical or machine learning model has access to data it shouldn't during the training process. This can lead to severe overestimation of a model's predictive performance.

Anyone can do post-publication peer review.
Anyone can be a steward of the scientific literature.
Anyone can do forensic metascience.
Anyone can sleuth.
That's why we are launching COSIG: the Collection of Open Science Integrity Guides, an open source resource for all of the above.
