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

objectivesWe aimed to describe treatment patterns of chronic lymphocytic leukaemia (CLL) patients in routine practice settings, compare overall survival and time-to-next-treatment among patients treated in different time periods (2005-2008, 2009-2013, 2014-2015), and explore associated factors.

methodsThis retrospective cohort study included adult CLL patients from the Finnish Hematology Registry.

resultsIn total, 124 and 64 CLL patients received first- and second-line treatments, respectively. The use of first- and second-line treatments with bendamustine-rituximab (BR) increased, while chlorambucil-based treatments decreased over time. Patients treated in more recent years showed a trend towards longer first- and second-line survival. A trend towards inferior overall survival was detected in first- and second-line treatment with B/BR. First-line time-to-next-treatment was longer for patients treated in the later years towards 2015, while second-line time-to-next-treatment did not improve over time.

conclusionsThis study identified that improved treatment outcomes over time were likely influenced by patient characteristics and treatments, but also through other factors unexplored in this study. Hence, further research on the factors influencing patients' survival over time is needed. In particular, research on using B/BR in clinical practice is warranted.
