Propensity score matching (PSM) successfully generated 41 well-balanced pairs. In the GEE\/GZLM analysis (which further corrected for residual baseline imbalances in alanine aminotransferase (ALT), aspartate aminotransferase (AST), and creatinine), IVIG treatment still failed to reduce the duration of glucocorticoid use (OR\u202f=\u202f3.229, 95% CI: 1.267\u20138.232), reduce glucocorticoid dosage (OR\u202f=\u202f2.653, 95% CI: 1.063\u20136.619), or shorten the length of hospital stay (OR\u202f=\u202f4.375, 95% CI: 1.581\u201312.108). Furthermore, subgroup analysis showed that in infants &amp;lt;6\u202fmonths of age, IVIG treatment did not shorten hospital stay and was not associated with glucocorticoid use outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>In conclusion, intravenous immunoglobulin (IVIG) treatment did not shorten hospital stays or reduce the use of glucocorticoids in children with severe respiratory syncytial virus pneumonia (SRSVP).
