Age distribution of carbapenem resistance proportions in A. baumannii complex isolates by gender. Age distribution of mean proportions (%) with corresponding 95% confidence intervals of carbapenem-resistant A. baumannii complex among all A. baumannii complex isolates (n = 35,821*) stratified by gender, expressed as mean proportions. Absolute numbers: Total: < 1 year (8/1,390), 1–19 years (31/2,379), 20–39 years (196/2,560), 40–59 years (365/5,911), 60–79 years (873/15,054), 80 ≥ years (159/8,527); Female: < 1 year (3/587), 1–19 years (14/1,201), 20–39 years (36/1,463), 40–59 years (101/2,324), 60–79 years (225/5,812), 80 ≥ years (66/4,491); Male: < 1 year (5/803), 1–19 years (17/1,178), 20–39 years (160/1,097), 40–59 years (264/3,587), 60–79 years (648/9,242), 80 ≥ years (93/4,036). *Only isolates with complete information on gender and age were included in this analysis
