Fig. 1: PRIDICT-BPD study design and serum proteomics.

a Overview of the PRIDICT-BPD cohort and blood sample collection, consisting of 49 appropriate for gestational age (AGA) and 18 small for gestational age (SGA) infants. Samples collected from infants and healthy adults were analysed using the proteomics workflow starting with serum sample preparation, followed by LC-MSMS analysis and data analysis. b Overview of the samples collected in cord blood (day 0) and from capillary or arterial blood (day 3, day 7, day 14, and day 28) in the PRIDICT-BPD cohort. c Histogram representing the coefficient of variation (CV) for all proteins quantified across repeated injections of a study wide quality control sample, with 874 proteins reliably quantified with high reproducibility (CV < 30%). d Label free quantification (LFQ)-intensity levels plotted for quantified haemoglobin subunits (zeta: HBZ; alpha: HBA1; beta: HBB; delta: HBD; gamma: HBG1/HBG2) and haptoglobin (HP) proteins across the technical replicates.
