From: Molecular epidemiology of pregnancy using omics data: advances, success stories, and challenges
Omics advancements featured in Row 1 literature overall, and Row 2 pregnancy investigation. Omics technology usage continues to grow in research studies. The number of publications by year with omics keywords and pregnancy in their abstract extracted from the PubMed database is shown in panel Row 2. The colors in the stacked bar charts show the trends of different specific omic technologies. For example, gas chromatography-mass spectrometry (GC–MS) has always been used in metabolomics. However, the use of liquid chromatography-mass spectrometry (LC–MS) is more common in recent years; for proteomics, mass spectrometry continues to be the dominant technique.
