title: [Analysis on factors related to X-ray outcomes in 93 SARS patients].
abstract: OBJECTIVE
  To study the related factors of the X-ray outcomes in recovered SARS patients.
  
  
  METHODS
  The X-ray results of 93 patients with SARS were studied retrospectively. The possible related factors analyzed were age, sex, body temperature at onset, range of the lesion, glucocorticoid administration time. The data were analyzed by chi square test.
  
  
  RESULTS
  Among all the patients with abnormal X-ray result, 19 were male (54.29%), 16 (45.71%) were female, P > 0.01; 7 (58.33%) were above the age of 45; 28 (34.57%) were below the age of 45, P > 0.01; hyperpyrexia (>/= 39), 26 (50.00%), below 39, 9 (21.95%); multiple-lesion, 22 (52.38%), mono-lesion, 13 (25.49%), P < 0.01; glucocorticoid administration time within 5 days, 22 (38.60%) after 5 days, 12 (33.33%), P > 0.01; within 7 days, 21 (30.00%), after 7 days, 14 (60.87%), P < 0.01.
  
  
  CONCLUSIONS
  The X-ray results of SARS were closely related to the severity of the disease (hyperpyrexia and bilateral lung field lesion). There was no significant correlation between X-ray result and the age or sex of the patients. Early use of glucocorticoid (within 5 days after onset), had no remarkable influence on the X-ray result. It was noted, however, the incidence of residual lesion in lung obviously increased if glucocorticoid was administered after 7 days of onset.
