Early decrease in blood lymphocyte count is associated with poor prognosis in COVID-19 patients: a retrospective cohort study

Table 3 Relationship between early (0–10 days) changes in lymphocyte count (10⁹/L) and death in COVID-19 patients (from GAMM)

β: the effect value of lymphocyte count over time; CI: confidence interval; Intercept: lymphocyte count at day = 0 and death = 0 (lymphocyte count at admission in the survival group); Day: the increasing value of lymphocyte count at death = 0 over time (changes in survival group lymphocyte count with length of hospital stay); Death: the difference of lymphocyte count at day = 0 between the group of death = 1 and the group of death = 0 (differences in lymphocyte counts between the surviving and non-surviving groups at admission); Day × death, the average increase in lymphocyte count daily under the condition of the group of death = 1 compared with the group of death = 0 (average difference in lymphocyte count changes between the surviving and non-surviving groups on a daily basis); Model I: adjusted for sex and age; Model II: adjusted for sex, age, white blood cell count, neutrophil count, lymphocyte count, history of hypertension, history of diabetes
