UpSet diagrams illustrating the reported number of isolated chest radiograph features and most frequent combinations of chest radiograph features by clinical TB case definitions for intrathoracic TB.(A) Confirmed Intrathoracic TB, (B) Unconfirmed Intrathoracic TB, (C) Unlikely Intrathoracic TB.

The horizontal bar charts on the bottom show the number of CRs where the select CR feature was present, whereas the vertical bar charts illustrate how often the CR feature was seen as the only isolated abnormality on the film (illustrated as single dot) and in combination with other abnormal CR features (illustrated as multiple connected dots). For CR reads where perihilar or paratracheal lymph nodes were classified as “uncertain,” the entire CR read was excluded from this representation.

Abbreviations: CR, chest radiograph; TB, tuberculosis.
