Fig 5. Frequency and relationship of words within annotated texts from teleconsultations.

(a) The time length of the call in an histogram and boxplot, that are divided into three groups: conventional, atypical and long. (b) The 6 most frequent terms in teleconsultations. The most frequent term is “asymptomatic” (35%), followed by runny nose (15%), sore throat (13%), dry caught (12%), flu syndrome (11%) and denies fever (7%). (c) Relations of words. Closer distances imply that terms were used together. We categorized 4 topics: suspect, asymptomatic, symptoms and doubts. The plot increases evidence on physician concerns about asymptomatic patients, as the symptoms topic appears together with the word “without”.
