1 · What the graph read from it

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.

2 · The registry

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

backgroundPopulation-based studies previously showed an improvement in overall survival (OS) for patients with diffuse large B-cell lymphoma (DLBCL) who received chemoimmunotherapy with rituximab. However, there is limited data (especially at the population level) that show a similar trend in OS improvement, in the most recent time period. We hypothesized that survival for DLBCL patients diagnosed in the United States has continued to improve in recent years and intended to measure outcome improvements.

methodsUsing the SEER-18 registries, we compared the incidence and relative survival rates (RSRs) of DLBCL patients between 2002-2007 and 2008-2013 (availability of novel agents, broader use of autologous hematopoietic cell transplantation and improvement in supportive care). Multivariable Cox regression models were used to assess associations between the year of diagnosis and OS while controlling for age, gender, stage, and ethnicity.

resultsThere were a total of 53 439 patients with DLBCL who were diagnosed between 2002 and 2013. Of these, 25 810 were diagnosed during time period-1 and 27 629 diagnosed during time period-2. There was a slight decline in incidence of DLBCL (time period-1 vs time period-2), 7.75 (95% CI = 7.66-7.84) vs 7.43 (95% CI = 7.34-7.52) cases per 100 000 persons, respectively (P < .0001). Overall, there was a modest improvement in DLBCL RSRs, with 5-year RSR improving from 61% (time period-1) to 64% (time period-2) and the improvement was noted across all subsets of patients. On multivariable analysis, patients diagnosed in time period-2 had lower mortality relative to time period-1 (HR = 0.87, 95% CI = 0.85-0.89).

conclusionsOur study shows an improvement in the outcomes of DLBCL patients beyond the introduction of rituximab, although the magnitude of improvement is small. It will be interesting to see the impact of chimeric antigen receptor-T cell therapy translating to population-level survival in the next 5 years.
