Comparison of intensity ratios of candidate lipids in the non-recurrent and recurrent groups (A: decreased and B: increased lipid species in the recurrent group). All the candidates demonstrated well-separated distributions between the two groups. Data are plotted as mean ± SD, along with individual data points. *P < 0.05, Welch’s t-test. Abbreviations: ID, identity number; LPC, lysophosphatidylcholine; SD, standard deviation; SM, sphingomyelin
