  1. Notes
  2. 1 Lymphocyte Count: The coefficient is negative, indicating that a higher lymphocyte count is associated with lower risk. Therefore, when calculating the total score, if the lymphocyte count is above a certain threshold (which needs to be determined based on actual data), a negative score is given (i.e., subtract 1 point). If it is below the threshold, no score is given or a positive score is given based on specific circumstances (but in this table, for simplification, we assume that all patients’ lymphocyte counts are below this threshold, so they all lose 1 point). However, in practical applications, a more refined approach may be to assign scores based on specific lymphocyte count values, such as dividing into several ranges, each corresponding to a different score
  3. 2 Other Risk Factors: For hypertension, immunosuppression, and lung lesions, if the patient has the risk factor, the corresponding score is given
  4. Risk Score Calculation:
  5. Add the scores for each risk factor the patient has, to obtain the total risk score
  6. Note that since the score for lymphocyte count is negative, when calculating the total score, if the lymphocyte count is above the threshold, the negative score needs to be subtracted from the total score (i.e., add 1 point because negative times negative equals positive). But in this simplified table, we assume that all patients’ lymphocyte counts result in them losing 1 point
  7. Risk Level Classification
  8. The higher the total score, the higher the risk of the patient developing persistent SARS-CoV-2 infection
  9. Different thresholds can be set based on the total score to classify risk levels, such as:
  10. Total score ≤ 1: low risk
  11. 2 ≤ Total score ≤ 3: moderate risk
  12. Total score ≥ 4: high risk
  13. Please note that the above risk level classification is based on a simplified risk scoring table and may need to be adjusted in practical applications based on more detailed data and clinical judgment
  14. Important Note:
  15. This risk scoring table is only an example, and it needs to be validated and optimized based on specific research data and clinical backgrounds when used in practice
  16. When using this table, please be sure to consider other factors that may affect the patient’s risk and assess the patient’s overall health status and medical history comprehensively
