Insignificance of surveillance imaging in patients with diffuse large B-cell lymphoma who achieved first complete remission: a retrospective cohort study.
Article in International journal of hematology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
The aim of this study was to evaluate the value of scheduled imaging for patients who achieved first complete remission after CHOP-like chemotherapy plus rituximab. In this retrospective cohort study, we included 759 patients newly diagnosed with de novo diffuse large B-cell lymphoma (DLBCL) at the Cancer Institute, Japanese Foundation for Cancer Research. Relapsed patients were divided into two groups based on method of diagnosis: clinical symptoms (symptom group, n = 57) or scheduled imaging (imaging group, n = 27). Our primary goal was to compare overall survival and relapse-free survival between the two groups. No significant difference in outcomes was found between the symptom and imaging groups. Median overall survival [7.5 years; 95% confidence interval (CI) 4.0-9.7 vs. 9.1 years; 95% CI 2.7 to not reached; P = 0.747), and median relapse-free survival (1.8 years; 95% CI 1.4-2.5 vs. 2.4 years; 95% CI 1.2-4.4; P = 0.108). Surveillance imaging in patients with DLBCL who achieved first complete remission did not demonstrate an advantage in terms of overall survival or relapse-free survival.
