Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:Whilst SARS-CoV-2 RNA has been detected on surfaces, one limitation to a molecular approach is the lack of information regarding infectivity. In a recent study by Zhou et al. (2020), no surface samples demonstrated infectivity. However, it was noted that the concentrations of SARS-CoV-2 on surfaces were below the current detection limits for culture methodologies (38). While there are known relationships between cycle threshold values and …

Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:Whilst SARS-CoV-2 RNA has been detected on surfaces, one limitation to a molecular approach is the lack of information regarding infectivity. In a recent study by Zhou et al. (2020), no surface samples demonstrated infectivity. However, it was noted that the concentrations of SARS-CoV-2 on surfaces were below the current detection limits for culture methodologies (38). While there are known relationships between cycle threshold values and probabilities of detecting viable virus in a sample (48, 49), it is necessary to know what fraction of detected genome copies relate to viral particles for QMRAs. More data are needed to better understand how molecular concentrations, even concentrations below detection limits, relate to infectivity and subsequent infection risk. Limitations: The model in this study only evaluates a surface transmission route while in reality, risks posed to healthcare workers are due combined exposure pathways: air, droplet, person-to-person, and surface transmission. As the model only evaluates surface transmission, these infection risks are likely to be an underestimate of the total risk incurred by healthcare workers over an entire shift. In a study of healthcare workers in a facility in Wuhan, China, 1.1% (110/9684) were COVID-19 positive (50). According to CDC, of 428,295 healthcare personnel for which data were available, 20% (84,035/428,295) were COVID-19 cases (51). However, it is not known how many shifts were associated with these infection rates....

Results from Barzooka: We found bar graphs of continuous data. We recommend replacing bar graphs with more informative graphics, as many different datasets can lead to the same bar graph. The actual data may suggest different conclusions from the summary statistics. For more information, please see Weissgerber et al (2015).
Results from JetFighter: We did not find any issues relating to colormaps.
