Questions

How strong is the evidence behind this?

Resolv rates this source "moderate evidence". Reasonable evidence with real limitations. It scores 59 out of 100 on our published rubric. The score is calculated from recorded facts about the source — study design, funding, publication venue, sample size, preregistration — not typed in by an editor.

What is the source for this?

Atypical antipsychotics for insomnia: a systematic review — Thompson W, et al. (2016). Published in: Reputable peer-reviewed journal. DOI: 10.1016/j.sleep.2016.04.003. The full source is linked on this page so you can read it yourself.

Who paid for this research, and does that matter?

Study design: Systematic review of randomised trials. Funding: Funding not disclosed. Independence from the proponent is not recorded. Industry sponsorship is one of the most reliably measured biases in medicine, which is why funding carries real weight in the score rather than sitting in a footnote.
