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
objectivesA diverse intratumoral T-cell receptor (TCR) repertoire is associated with improved survival in diffuse large B-cell lymphoma (DLBCL) treated with rituximab/cyclophosphamide/doxorubicin/prednisolone/vincristine (R-CHOP) chemoimmunotherapy. We explored the impact of intratumoral TCR repertoire on interim PET (iPET) done after four cycles of R-CHOP, the relationships between intratumoral and circulating repertoire, and the phenotypes of expanded clonotypes.
methodsWe sequenced the third complementarity-determining region of TCRβ in tumor samples, blood at pre-therapy and after four cycles of R-CHOP in 35 patients enrolled in ALLGNHL21 trial in high-risk DLBCL. We correlated the TCR diversity metrics with iPET status, gene expression profiles and HLA-class I genotypes. We then sequenced the FACS-sorted peripheral blood T cells in six patients, and pentamer-sorted EBV-specific CD8
resultsCompared with iPET
conclusionThis study demonstrates that clonally expanded intratumoral TCR repertoires are associated with iPET
