Limitations and notes

Seventy-two of 93 treated eyes had 12-month follow-up; the ±0.50 D analysis was reported for 37 emmetropia-targeted eyes.

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.
