α-tocopherol/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.
No detected effect on incidence of stroke
Very limitedEvidence strength: very limited. Human evidence with major recorded weaknesses, or non-human, uncontrolled or unverified evidence.FindingNull resultreplicated ×1“The pooled results showed no significant benefit in the vitamin E group with respect to stroke of any type (RR 1.01; 95% confidence interval [CI]: 0.96, 1.07); ischaemic stroke (RR 1.01; 95% CI: 0.94, 1.09), haemorrhagic stroke (RR 1.12; 95% CI: 0.94, 1.33), fatal stroke (RR 0.94; 95% CI: 0.77, 1.14), and non-fatal stroke (RR 0.99; 95% CI: 0.91, 1.08).”
