Abstract
Abstract Background: The coronavirus disease 2019(COVID-19) had become an epidemic and spread across the world, lead to severe respiratory failure and death. Traditional Chinese Medicine(TCM), Such as Lianhua Qingwen has been widely used in the prevention and treatment of COVID-19, This systematic review and meta-analysis will assess the effects of traditional Chinese herbal medicine(Lianhua Qingwen) in COVID-19 pneumonia from the randomized controlled trials(RCTs) and case control studies(CCSs). Method: we search the literatures in databases inculding PubMed, Embase, Web of science, Cochrane Library, Wanfang, Chinese Science and Technology Periodical Database (VIP), Chinese Biomedical Literature Database (CBM) and China National Knowledge Infrastructure(CNKI) , setting the date from December 1, 2019, to June 1, 2021, Cochrane Risk of Bias tool and the Newcastle-Ottawa Scale were used to assess the quality of randomized controlled trials. All analyses were conducted by Stata 14.0. Results: nine studies with 1163 patients(616males) were included, six were RCTs, three are CCSs. Compared with patients treated by western medicine alone, patients treated by Lianhua Qingwen combined with western medicine have a higher overall effective rate[RR=1.20, 95%CI1.20(1.11, 1.31), P =0.000], cardinal symptom disappearance rate[disappearance rate of fever: OR:3.64, 95%CI(1.57, 8.47), P=0.001;disappearance rate of cough: OR:1.97, 95%CI(1.45, 2.68), P=0.001; disappearance rate of fatigue: OR:2.55, 95%CI(1.09, 5.99), P=0.032] and CT recovery rate[RR:1.25, 95% CI (1.13,1.38), P= 0.000], reduce the rate of the progress into severe diseases of COVID-19 patients[RR:0.43, 95%CI(0.30, 0.62), P =0.000], with more shorter duration of fever[WMD=-1.07，95%CI(-1.77, -0.37), P =0.003], The including studies described that Lianhua Qingwen did not increase the adverse drug reactions. Conclusion: Lianhua Qingwen may have advantages in improving the clinical effective rate and cardinal symptom disappearance rate. Besides, it also had an excellent effect on the improvement of the chest CT and the proportion reducing of progress into severe clinical disease, which could be used as an effective therapy for COVID-19.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
