What is the correct way to punctuate the words ‘worse even’?

I’m unsure if this is written as:

‘Worse even, than...’

‘Worse, even, than...’

‘Worse, even than...’

Or without commas at all.

I tried looking it up, but all I can find are examples of the usage of ‘worse still’ and ‘even worse than’.


Even has been inserted into the phrase worse than, so I would put a comma on each side of it.
