Meta-Analysis: Variation in False-Negative Rate of Reverse Transcriptase Polymerase Chain Reaction–Based SARS-CoV-2 Tests by Time Since Exposure
Description
A dataset summarizing the variation in false-negative rates of reverse transcriptase polymerase chain reaction (RT-PCR)–based SARS-CoV-2 tests as a function of time since exposure.
Format
A data frame with 410 rows and 11 columns. Each row represents the results from a study. The columns include:
- study
Name of the author conducting the study.
- test
Type of testing performed.
- day
Number of days since symptom onset.
- day_min
Minimum number of days since symptom onset. Applicable for studies by Guo et al. and Kim et al.
- day_max
Maximum number of days since symptom onset. Applicable for studies by Guo et al. and Kim et al.
- n
Total number of tests conducted on a given day.
- test_pos
Number of positive test results.
- inconclusive
Number of inconclusive test results. Applicable for studies by Kujawski et al. and Danis et al.
- nqp
Number of positive but non-quantifiable test results, where the viral load is below the quantification threshold of log10(1) copies/1000 cells.
- pct_pos
Proportion of positive tests expressed as a percentage.
