In the HYVET trial, antihypertensive treatment with sustained-release indapamide, with or without perindopril, reduced death from any cause by 21% (95% CI, 4 to 35; P=0.02) among patients aged 80 years or older.

Notes on verification

Directly matches the primary published HYVET trial results (Beckett et al., NEJM 2008), consistently cited in subsequent guidelines and reviews without contradiction.
