Although the incidence and mortality rates of ILD and PS have increased following the COVID-19 pandemic, comprehensive research examining their burden and associated risk factors remains limited. Therefore, the present study aimed to analyze the spatiotemporal distribution, gender-specific and age-related disparities, and sociodemographic determinants of ILD and PS from 1990 to 2021 to facilitate evidence-based targeted interventions.</p><p><strong>Methods: </strong>By using data from the Global Burden of Disease 2021 database, we analyzed age-standardized incidence rate (ASIR), age-standardized mortality rate (ASMR), and age-standardized disability-adjusted life year rate (ASDR) across 204 countries/regions. Temporal trends were evaluated using average annual percentage change (AAPC), age-period-cohort (APC), and Bayesian APC (BAPC) models. Decomposition analysis and Pearson's correlation analysis were conducted to assess the impact of aging, population growth, and sociodemographic index (SDI).

While dual bronchodilators (LAMA/LABA) and inhaled corticosteroid combination therapies (ICS/LABA) alleviate symptoms, patients continue to face elevated risks of all-cause mortality and cardiovascular events. Recent studies suggest that triple therapy (ICS/LAMA/LABA) may improve outcomes by reducing acute exacerbations and systemic inflammation. However, its long-term effects on mortality and cardiovascular safety remain controversial, highlighting the critical need for systematic evidence to inform clinical decision-making.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;A systematic search of PubMed, Embase, and the Cochrane Library (up to July 2024) identified 13 randomized controlled trials (RCTs) comparing triple therapy with dual therapies (LAMA/LABA or ICS/LABA) in patients with moderate-to-severe COPD. Outcomes included all-cause mortality, exacerbation rates, and cardiovascular adverse events of special interest (CVAESI). Risk ratios (RR) with 95% confidence intervals (CI) were calculated using fixed- or random-effects models based on heterogeneity (assessed via I² statistics). Subgroup analyses explored heterogeneity across drug combinations, supplemented by sensitivity analyses and publication bias assessments.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Compared to LAMA/LABA dual therapy, triple therapy significantly reduced all-cause mortality (RR = 0.76, 95% CI = 0.60-0.97, p = 0.03), moderate-to-severe exacerbation risk (RR = 0.93, 95% CI = 0.90-0.97, p = 0.0003), and overall CVAESI incidence (RR = 0.75, 95% CI = 0.61-0.93, p = 0.008), with a 38% reduction in severe CVAESI (hospitalized or fatal events: RR = 0.62, 95% CI = 0.45-0.86, p = 0.004). Subgroup analyses demonstrated that the BGF regimen achieved superior reductions in CVAESI (RR = 0.72, 95% CI = 0.58-0.89, p = 0.003) and severe CVAESI (RR = 0.61, 95% CI = 0.47-0.79, p = 0.0002) compared to other triple therapies. Although BGF showed only a nonsignificant trend toward mortality reduction (RR = 0.77, 95% CI = 0.58-1.03, p = 0.08), it exhibited greater efficacy in reducing exacerbations (RR = 0.72 vs. non-BGF regimens) and cardiovascular risks. Non-BGF triple therapies yielded inconclusive results due to limited sample sizes and substantial heterogeneity (I²=62-83%, subgroup difference p &lt; 0.05). Sensitivity analyses confirmed the stability of pooled estimates (&lt; 5% variation upon study exclusion), with no significant publication bias detected via funnel plots or Begg's test (p &gt; 0.05).&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusion: &lt;/strong&gt;This study confirms that ICS/LAMA/LABA triple therapy significantly reduces mortality, exacerbations, and cardiovascular risks in moderate-to-severe COPD compared to LAMA/LABA dual therapy.
