### Study Selection  
The database search identified 251 potentially relevant articles (Scopus: 109; Web of Science: 58; Science Direct: 46; PubMed: 38). After removing 116 duplicates, 135 articles were screened at the title/abstract level. Following full-text review, 70 studies met all inclusion criteria (Figure 1). The main reasons for exclusion were incomplete IEQ parameter coverage (n = 31), simulation-based studies (n = 12), review articles (n = 9), and insufficient data reporting (n = 13). Table 1 presents the complete overview of the 70 studies included in this review. \begin{table}
