SARS-CoV-2 (acute respiratory syndrome coronavirus 2): result of the exam for SARS-CoV-2 RT-PCR (0 = negative; 1 = positive) (reverse transcription – polymerase chain reaction).
N, Cases included in the analysis; B, coefficient of the univariate logistic regression; P, coefficient significance; OR, odds ratio (exp(B)); CI, confidence interval. MCH, mean corpuscular haemoglobin; MCHC, mean corpuscular haemoglobin concentration; MCV, mean corpuscular volume; MPV, mean platelet volume; RDW, red blood cell distribution width; zName, means that the variable was converted and made available in a standardised format (mean = 0; standard deviation = 1).
Age was converted in quantiles in the range of 0−19, mean value is 9.32.
Blood tests selected for screening as potential predictors of COVID-19 inflammation.
