Large mediastinal tumor mass as a prognostic factor in Hodgkin's lymphoma. Is the definition on the basis of a chest radiograph in the era of CT obsolete?

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeThe risk factor "large mediastinal tumor mass" is an internationally accepted unfavorable prognostic factor in the staging of Hodgkin's lymphoma (HL). The definition of this risk factor varies considerably between large cooperative study groups. The purpose of the present analysis was to determine to which degree data obtained from chest radiograph (CRX) give the same results as those from CT scans (CT).
methodsA total of 145 de novo HL patients in early unfavorable and advanced stages were included in this study. A total of 94 patients had a large mediastinal tumor mass according to the guidelines of the German Hodgkin Study Group (GHSG), while 51 had mediastinal lymph node involvement only. The size of mediastinal involvement and the thoracic diameter were measured on CRX and CT. Agreement between CRX and CT was determined by sensitivity and specificity analysis as well as descriptive statistics and correlations.
resultsThe correlation of the diameters on CRX with those of CT was 0.95 for the tumor size and 0.77 for the thoracic diameter. The diagnostic decision-large mediastinal mass or not-correlated with 0.81 between CRX and CT and was identical in 90.3% of cases. The sensitivity was 0.87 and the specificity 0.96 for CRX, which is considered the current standard.
conclusionThe results show that there is a high agreement between the measurements of CRX and CT. Diagnosis of a large mediastinal mass disagreed in 10% of patients. Since the correct diagnosis of this risk factor is decisive for the adequate multimodal treatment choice, CRX should not be omitted.
