Overview of child participants and chest radiographs included in this analysis.

CR, chest radiograph; Rx, treatment; TB, tuberculosis.

¹CR read based on assessment of anteroposterior or posteroanterior film with/without lateral film.

²Each child had 1 CR and each CR generated 2 individual CR reads, so that the number of CR reads was double the number of CRs and double the number of child cases.

³Confirmed, unconfirmed, and unlikely intrathoracic TB as per standard clinical case definitions (Graham et al. [11]).
