But if they are outpatients is there any guarantee that they were even sticking to a low sodium diet in the first place?

- Ensorceled 4y agoSo you are saying they are lying in the title when they say "randomised, controlled trial"?
- DoingIsLearning 4y agoYou can still have an RCT with self-reported data. The issue being that self-reported is not always accurate.

The study group decreased median sodium intake by 27% compared to the 'control' group who decreased intake by 2%. There's always a issue of 'the human element' in studies like this where people lie and don't follow instructions but claim they did, but good study design and follow-through typically minimize those issues. > Between baseline and 12 months, the median sodium intake decreased from 2286 mg/day (IQR 1653–3005) to 1658 mg/day (1301–2189) in the low sodium group and from 2119 mg/day (1673–2804) to 2073 mg/day (1541–2900) in the usual care group.
