Sleep-disordered breathing is linked to some poorer outcomes after ischemic stroke
Observational studies linked disrupted breathing during sleep to hospitalization and death, but did not detect significant associations with recurrent stroke, cognitive impairment or complications.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
In people with ischemic stroke, sleep-disordered breathing was associated with higher odds of hospitalization and death. The review did not find statistically significant links with cognitive impairment, complications or another stroke. Because the included studies were observational, these results cannot establish that breathing problems caused poorer outcomes or that treating them would improve recovery.
The estimates for hospitalization and death had wide confidence intervals. The abstract does not report follow-up periods or define comparison groups, and its observational design leaves causal explanations unresolved.
Results differed by outcome
The review pooled associations with several outcomes after ischemic stroke. Its positive findings for hospitalization and mortality should be considered separately from the outcomes for which no statistically significant association was detected.
Understanding the null results
A nonsignificant result does not prove that an association is absent. In particular, uncertainty around the recurrent-stroke estimate was wide, so the review cannot rule out meaningful differences in either direction for that outcome.
