The Claim
The inclusion of preoperative respiratory sarcopenia in clinical prediction models significantly improves the reclassification of patients at risk of impaired functional recovery after cardiovascular surgery, as measured by a net reclassification improvement of 0.36 and an integrated discrimination improvement of 0.037.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Adding a measure of muscle weakness in the breathing muscles before heart surgery improves the accuracy of models that predict which patients will have trouble recovering their physical function after surgery.
See the scientific wording
Adding preoperative respiratory sarcopenia to clinical prediction models significantly improves the ability to reclassify patients at risk of impaired functional recovery after cardiovascular surgery, as demonstrated by a net reclassification improvement of 0.36 and integrated discrimination improvement of 0.037.
When the breathing muscles are weak and thin before surgery, the body cannot move enough air after the operation, which lowers oxygen levels in the blood and prevents muscles throughout the body from getting the energy they need to recover.
What the research says
1 studyDoctors can better predict which heart surgery patients will struggle to recover physically by checking their breathing muscle strength and diaphragm thickness before surgery—this simple addition makes their predictions much more accurate.
