Example of a single patient’s time series laboratory biomarker data. Covid +ve indicates the time of a COVID-19 positive test. See Table 1 for biomarker abbreviations. Biomarkers vary widely in units of measurement. As a simple indication of upward and downward movement of readings, variation in biomarker measures are visualised from low (purple/black) to high (orange/yellow) created by subtracting the minimum value and normalizing the readings to span 0 to 1
