Context:
Doh! Top Science Journal Retractions of 2011
......
Each year hundreds of peer-reviewed scientific articles are retracted. Most involve no blatant malfeasance; the authors themselves often detect errors and retract the paper. Some retractions, however, as documented on the blog Retraction Watch, entail plagiarism, false authorship or cooked data.
Does "no blatant" mean "insignificant"?
Not exactly. Definition of blatant | Collins English Dictionary.
Context is always important; labelling is rarely important.
