Ugandan geriatrician outlines risk (6)

I believe the answer is:

danger

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

'risk' is the definition.
(I know that risk can be written as danger)

'ugandan geriatrician outlines' is the wordplay.
'DANGER' is hidden in amongst the letters.
However, I am not sure how the hidden word is indicated.

Can you help me to learn more?

(Other definitions for danger that I've seen before include "Red flag, for example" , "Peril, threat" , "'Peril, risk (6)'" , "Insecurity" , "Garden (anag) - peril" .)

I've seen this clue in The Irish Times.
