Medical Evaluation of Test Results Related To Covid 19 in Iranian Hospitals Using Quadas-2 To Evaluate the Quality of Studies and Meta-Analysis Using Stata / Mp V.16 Software

The aim of current study was to evaluate the outcome of some laboratory tests and accuracy of diagnostic tests for patients with covid-19. the quadas-2 tool was utilized to quality assessment of diagnostic accuracy studies. for data extraction, two reviewers blind and independently extracted data from abstract and full text of studies that included. 95% confidence interval for effect size with fixed effect model and inver-variance method were calculated. meta-analysis was performed using stata/mp v.16 software. 469 studies were reviewed, of which the full text of 52 studies was reviewed and finally twenty-two studies were selected for meta-analysis. mean differences of alanine transaminase was 3.40 u/l (md, 95% ci -2.45, 9.25), correlation between alanine transaminase and severe covid-19 was not significantly. stool, feces, rectal swabs 25% (es, 95% ci 0.32, 0.82), urine 1% (es, 95% ci 0.05, 0.58), overall sensitivity of pcr for detection of covid-19 was 44% (es, 95% ci 0.19, 0.68), less sensitive observerd when pcr detection of covid-19. evidence revealed that at the time of admission of patients with covid-19, a specific laboratory model can be used to perform relevant tests and make decisions about patients. pcr using sputum samples was highly sensitive for detecting covid-19 and after that computed tomography of the chest was identified with high sensitivity.
