Table 2 Relationship between the anesthesia method and the presence of residual blast cells in peripheral blood by inverse probability of treatment weighting (IPTW) using propensity score

From: Association between the choice of anesthesia method and reactivity to chemotherapy in children with acute lymphocytic leukemia: a preliminary retrospective cohort study

  Before weighting After weighting
Group S (n = 19) Group P (n = 38) Crude OR (95% CI) P value Adjusted OR (95% CI) P value
Residual blasts 7 (36.8) 26 (68.4) 0.27 (0.085–0.86) 0.045 0.61(0.16–2.3) 0.47

  1. Data are expressed as n (%) or median (25th–75th percentile). Group S patients received general anesthesia with sevoflurane and group P received propofol. Residual blasts: number of patients in whom leukemic blast counts in peripheral blood on day 8 following prednisone chemotherapy were > 0/μL. Blast count: leukemic blast cell count in peripheral blood on day 8 following prednisone chemotherapy
