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

backgroundPrimary cutaneous lymphomas (PCL) are primarily composed of cutaneous T-cell lymphomas (CTCL), followed by cutaneous B-cell lymphomas (CBCL). This study aimed to assess the incidence and survival rates of PCL in Germany.

methodsWe analyzed data from the North Rhine-Westphalia Cancer Registry (2008-2021), which covers a population of 18 million. Age-standardized incidence rates and relative survival were calculated.

resultsThe analysis included 3,853 patients with newly diagnosed PCL. Of these, 69.5% were CTCL, and 24.9% were CBCL. The age-standardized incidence of PCL was 10.8 per million person-years. The incidence of both CTCL and CBCL increased over time. PCL cases were also identified in children. The overall five-year relative survival for PCL was 89% (95% CI: 87-92%), with CTCL patients having a survival rate of 91% (95% CI: 88-94%) and CBCL patients of 86% (95% CI: 81-91%). Among patients with Sézary syndrome, the five-year relative survival was 53% (95%: CI:29-77%).

conclusionsThis study represents the largest population-based analysis of PCL in Germany, including both adults and children. The incidence of PCL was higher than previously reported. Additionally, we present the first survival data for PCL in Germany, revealing a notably higher survival probability for patients with Sézary syndrome.
