Id Subject Object Predicate Lexical cue
T3 0-10 Sentence denotes Objectives
T4 11-114 Sentence denotes To explore the relationship between the imaging manifestations and clinical classification of COVID-19.
T5 116-123 Sentence denotes Methods
T6 124-208 Sentence denotes We conducted a retrospective single-center study on patients with COVID-19 from Jan.
T7 209-225 Sentence denotes 18, 2020 to Feb.
T8 226-251 Sentence denotes 7, 2020 in Zhuhai, China.
T9 252-492 Sentence denotes Patients were divided into 3 types based on Chinese guideline: mild (patients with minimal symptoms and negative CT findings), common, and severe-critical (patients with positive CT findings and different extent of clinical manifestations).
T10 493-700 Sentence denotes CT visual quantitative evaluation was based on summing up the acute lung inflammatory lesions involving each lobe, which was scored as 0 (0%), 1 (1–25%), 2 (26–50%), 3 (51–75%), or 4 (76–100%), respectively.
T11 701-776 Sentence denotes The total severity score (TSS) was reached by summing the five lobe scores.
T12 777-824 Sentence denotes The consistency of two observers was evaluated.
T13 825-879 Sentence denotes The TSS was compared with the clinical classification.
T14 880-955 Sentence denotes ROC was used to test the diagnosis ability of TSS for severe-critical type.
T15 957-964 Sentence denotes Results
T16 965-1022 Sentence denotes This study included 78 patients, 38 males and 40 females.
T17 1023-1120 Sentence denotes There were 24 mild (30.8%), 46 common (59.0%), and 8 severe-critical (10.2%) cases, respectively.
T18 1121-1220 Sentence denotes The median TSS of severe-critical-type group was significantly higher than common type (p < 0.001).
T19 1221-1287 Sentence denotes The ICC value of the two observers was 0.976 (95% CI 0.962–0.985).
T20 1288-1392 Sentence denotes ROC analysis showed the area under the curve (AUC) of TSS for diagnosing severe-critical type was 0.918.
T21 1393-1458 Sentence denotes The TSS cutoff of 7.5 had 82.6% sensitivity and 100% specificity.
T22 1460-1471 Sentence denotes Conclusions
T23 1472-1604 Sentence denotes The proportion of clinical mild-type patients with COVID-19 was relatively high; CT was not suitable for independent screening tool.
T24 1605-1718 Sentence denotes The CT visual quantitative analysis has high consistency and can reflect the clinical classification of COVID-19.
T25 1720-1730 Sentence denotes Key Points
T26 1731-1829 Sentence denotes • CT visual quantitative evaluation has high consistency (ICC value of 0.976) among the observers.
T27 1830-1929 Sentence denotes The median TSS of severe-critical type group was significantly higher than common type (p < 0.001).
T28 1930-2057 Sentence denotes • ROC analysis showed the area under the curve (AUC) of TSS for diagnosing severe-critical type was 0.918 (95% CI 0.843–0.994).
T29 2058-2123 Sentence denotes The TSS cutoff of 7.5 had 82.6% sensitivity and 100% specificity.
T30 2124-2262 Sentence denotes • The proportion of confirmed COVID-19 patients with normal chest CT was relatively high (30.8%); CT was not a suitable screening modality
