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

Routine follow-up for diffuse large B-cell lymphoma have been shortened to 2 years when event-free survival at 24 months (EFS24) emerged as a new milestone. In the present study, we aimed to determine whether the achievement of this milestone affected overall survival (OS). We compared OS to that of an age- and sex-matched population, analysed other factors governing OS, and reviewed the causes of death. Data were collected from the Swedish Cancer Registry and from individual patient's records. We included 1169 adult patients from five counties between the years 2001 and 2014. The median (range) age was 64·6 (18-91) years, 56·6% were men and the median follow-up was 82·3 months. For early stages, the achievement of EFS12 did not improve OS. More than two-thirds of the patients (n = 837, 71·6%) achieved EFS24, of which 190 (22·7%) died during follow-up. Lymphoma (20%), cardiovascular disease (22·4%) and malignancies (16%) contributed to causes of death. Patients aged <60 years had an OS that matched the standard population. In multivariate analysis, only age >60 years significantly affected OS after EFS24 compared with the standard population. We concluded that follow-up beyond EFS24 should be considered for patients aged >60 years.
