Note. The Newcastle-Ottawa Scale assesses bias and methodological quality by assigning a score from 0 to 9 stars across three domains: selection of patients and controls, comparability between groups, and outcome and follow-up. Studies are categorized as poor quality (0–2 stars), fair quality (3–5 stars), or good/high quality (6–9 stars)
