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
Classic Hodgkin lymphoma (CHL) is a lymphoid neoplasm deriving from B cells in a rich inflammatory background. There are four histological subtypes with different epidemiological features. Bone marrow involvement by CHL is infrequent, and subtyping CHL from the bone marrow is not suggested as there might be discordant histopathology between the primary tumors and bone marrow specimens. In this study, we aimed to identify the histopathological features of bone marrow involved by CHL and tried to correlate these features with their subtypes. Among the 23 recruited cases, the frequencies of mixed cellularity (MC; 48%, 11/23) and nodular sclerosis (NS; 44%, 10/23) were similar. There were two patterns of marrow involvement: pattern A (fibrous), space-occupying lesions with alternating hypo- and hypercellular areas against a fibrotic background with dilated sinusoids and pattern B (histiocyte-rich), ill-defined granuloma-like lesions in which histiocytes merged with normal hematopoietic and inflammatory cells. Pattern A was more frequent in patients with CHL-NS than CHL-MC (100% vs. 18.2%; p < 0.001). Diagnostic Hodgkin cells and Reed-Sternberg (HRS) cells were identified in all cases, while HRS variant lacunar cells were occasionally discovered, particularly in the CHL-NS subtype (NS 100% vs. MC 9%; p < 0.001). The frequency of EBV association was higher in MC (64%) than that in NS (36%) subtype, but not statistically significant. Of the two patterns of marrow involvement, pattern A was more commonly associated with the NS subtype and less frequently associated with EBV. Recognizing the patterns of marrow involvement is important for diagnosis and may contribute to the subtyping of CHL.
