caffeine/Finding
One finding, on its own
A single claim from the graph, with the evidence strength computed from its study, the sentence it was drawn from, and the paper. This address does not change.
Increases sleep onset latency
Very limitedEvidence strength: very limited. Human evidence with major recorded weaknesses, or non-human, uncontrolled or unverified evidence.Findingreplicated ×1“Random-effects meta-analysis showed that caffeine significantly reduced total sleep time (mean difference [MD] = -34.67 min), sleep efficiency (MD = -4.74 %), and slow-wave sleep proportions (SWS%) (MD = -1.01 %), while prolonging sleep onset latency (MD = +8.35 min).”
