tattier

I'm a little stuck... Click here to teach me more about this clue!

'more neglected' is the definition.
Both the definition and answer are comparative adjectives. Maybe you can see a link between them that I don't see?

'stats uncovered by bank' is the wordplay.
'uncovered' says to take the centre.
'by' is a charade indicator (letters next to each other).
'bank' becomes 'tier' (both can mean a row of similar things).
The central letters of 'stats' are 'tat'.
'tat'+'tier'='TATTIER'

Can you help me to learn more?

(Another definition for tattier that I've seen is " More shabby".)
