Prospective cohort study

Medical records

273

273 diagnosed COVID-19 patients with mild category in Shanghai Public Health Clinical Center were included in this analysis.

The average age of 273 COVID-19 patients enrolled with imaging progression were older than those without imaging progression (p = 0.006). The optimal cutoff of age for predicting imaging progression on chest CT was 51 years.

Total

7 Day


COVID-19 (severe/critical)

71

71 COVID-19 patients suffered from imaging progression on chest CT at first week after admission, and the other 202 patients were imaging progression-free on chest CT.


Laboratory Findings

Monocyte–Lymphocyte ratio

systemic inflammatory markers

Yes

Age, gamma globulin therapy, thymosin therapy, Monocyte-lymphocyte ratio (MLR), serum cystatin C, homocysteine, estimated glomerular filtration rate (eGFR) and period from onset to admission.


Age, MLR, homocysteine and period from onset to admission could predict imaging progression on chest CT from COVID-19

Good

Yes
