Label protocol
PCR assay were performed using a miRCURY LNA miRNA Custom PCR Panel Catalog#YCA25430 (Qiagen) following the manufacturers instructions. Reverse transcription was performed from 5ยต L total RNA using the miRCURY LNA RT Kit (Qiagen). Quantitative real-time PCR were performed (Applied Biosystems ViiA 7) with 40 cycles at 95C for 10 seconds and 56C for 60 seconds.

Data processing
The raw data (raw CT) values were input into GeneGlobe with a CT cutoff value of 33. In the GeneGlobe preprocessing, all CTs greater than 33 were changed to a value of 33 and the CTs were adjusted for the interplate calibrator (UniSp3) according to the miRCURY LNA miRNA PCR Panels & Assays Data Analysis Handbook. Normalization values for each sample were calculated using the NormFinder method in GeneGlobe. The microRNAs used for normalization of serum samples included: miR-107, miR-24-3p, let-7i-5p, miR-19b-3p, miR-16-5p, miR-320a, miR-23a-3p, miR-21-5p, let-7b-5p, and miR-25-3p. The microRNAs included for normalization of serum EV samples included: included hsa-miR-107, hsa-miR-24-3p, hsa-miR-30c-5p, hsa-miR-93-5p, hsa-let-7i-5p, hsa-miR-222-3p, hsa-miR-27a-3p, hsa-miR-23a-3p, hsa-miR-21-5p, and hsa-miR-27b-3p. These normalized values were then used to make comparisons between groups (adverse pathology versus not adverse pathology) to determine significantly different microRNAs using p < 0.05 The significant microRNAs were then used to generate random forest models to predict adverse pathology The Fold Change Template shows the p-values for each microRNA. The microRNAs with p<0.05 were included in the random forest model to predict adverse pathology.
