	miRNA with decreased expression in N2 L3 larva comparing to in N2 L2 larva.	DEGseq and GFOLD were used to analyze miRNAs expression. Authors chose miRNAs which had more than two-fold difference in expression (P < 0.001, q < 0.01 of Storey) from DEGseq, and miRNAs which had more than two-fold difference in expression (GFOLD score > 0 for up-regulation and GFOLD score < 0 for down-regulation) from GFOLD outcomes. Then authors obtained the intersection of up-regulated miRNAs and down-regulated miRNAs for each stage from the chosen miRNAs, respectively.	WBPaper00045316:miRNA_N2_L3_vs_L2_downregulated_adult
	Micro RNAs that showed significantly increased expression in day 8 adults comparing to in day 1 adults in coelomocyte.	Differentially expressed miRNAs were identified using DEGseq based on unique molecular identifier (UMI). A minimum UMI sum of 10 in 3 replicates was set as the threshold of expression. MiRNAs with more than five reads were defined as expressed. Differential expression of miRNAs was analysed by t-test (P value < 0.05 and fold-change > 1.5 or < 0.67) after Box-Cox transformation. MiRNA targets were identified by TargetScanWorm (Release 6.2) and Pearson Correlation Coefficient smaller than -0.2.	WBPaper00066447:Day8_vs_Day1_upregulated_coelomocyte

	miRNAs in F1 generation down regulated by exposure to 20uM and 20mM nicotine during F0 generation.	Statistical analysis was based on t-test for independent samples via SPSS to compare each of the nicotine treatments with control (i.e. low vs. control and high vs. control). Welch test correction was performed to account for unequal variance in each of the compared groups (control and treatment). In addition, to increase the statistical stringency, miRNAs differential expression was deemed significant only if it fulfilled two criteria: p value , 0.05 and expression changed by at least 50% relative to control.
