Limitations and notes

Normal-OSDI percentages are reported exactly from the PubMed abstract; observed denominators were not supplied and are not inferred.

Missing fields are not interpreted as negative findings. Arm counts may not be additive in all study designs.

Study evidence level
A simple, non-GRADE hierarchy based on design: randomized and large regulatory trials are high; prospective cohorts moderate; retrospective observational studies low. Manual review can override this label.
