The difference between the percentage of males and females operated on for these CHDs was compared between the IQIC and in the United States (KID 2012).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Findings<\/jats:title>\n                    <jats:p>Of 108,439 surgical admissions, 54.4% (59,021\/108,439) were males. After adjusting for case mix, no statistically significant differences in odds ratios for mortality or infection by sex were found, although females had a lower risk of death in lower complexity and higher risk of infection in higher complexity surgeries. Six lesions analysis revealed higher odds of mortality in females for ventricular septal defect repair and higher risk of major infection for coarctation repair and the arterial switch operation compared with males. For 5 of the 6 lesions, fewer females underwent surgery in IQIC compared with the United States.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Interpretation<\/jats:title>\n                    <jats:p>Our findings suggest that female children in LMIC have unequal access to CHD surgery compared with males with few postoperative differences in mortality or infection.
