For how we live.
The only systematic review to pool the trials found a warm shower or bath in the evening does speed sleep onset — but the effect is modest and depends on timing the heat one to two hours before bed.
The largest network meta-analysis of brain stimulation found several forms of TMS roughly triple the odds of responding, but they sit below ECT and rest on mostly small, uncertain trials.
Two meta-analyses find evening exercise leaves sleep largely unchanged or slightly improved. The real exception is vigorous exercise finishing within about an hour of bedtime.
In the largest network meta-analysis, EMDR and trauma-focused CBT were the most effective treatments for adults with PTSD. The evidence is graded moderate-to-low, and the eye movements may not be why it works.
A review of 41 studies found that the great majority of AI medication-adherence prediction models carried high risk of bias, and that fancier algorithms did not reliably predict better.
ABYSS and SMART-DECISION together cover 6,238 stable patients. Discontinuation cleared both noninferiority margins, though the authors say the primary endpoint's composition limits what it shows.
An updated systematic review of 25 randomised trials found small effects, concentrated in neuropathic pain, alongside moderate to large increases in dizziness, sedation and nausea. Long-term data barely exist.
The pooled effect on self-reported stress was g = -0.35 from 785 participants. The authors of the meta-analysis warn against a miscalibration between the hype and the evidence — their phrase, not ours.
A network meta-analysis of 331 trials and 34,285 adults found no significant differences between the main psychotherapies, with one exception. In children and adolescents the picture is narrower.
A network meta-analysis of 101 trials and 11,910 patients found no significant difference between psychotherapy and medication for adult depression — and a consistent advantage for combining them.
