Fractional laser vs non‐fractional non‐ablative laser: Participant‐reported scar improvement (short‐term) N of participants with > 50% improvement in acne scars
- Population
- people with acne scars
- Intervention
- Fractional laser
- Comparison
- non‐fractional non‐ablative laser
- Outcome
- Participant‐reported scar improvement (short‐term) N of participants with > 50% improvement in acne scars
It is very uncertain whether fractional laser changes participant‐reported scar improvement (short‐term) N of participants… compared with non‐fractional non‐ablative laser (very low certainty).

How reviews are matched to this question
Reviews word the same question differently. Four decision models (TypeSafe's Jev, Liquid AI's d1-ultra, SubQ Snap and Baseten's Elephant) judged each wording of the population, intervention, comparator and outcome against the others; two wordings count as the same when at least three of them agree and none clearly disagrees, and findings count as this question only when all four elements match. Timing, setting and subgroup never split a question: they are shown on each finding.
