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

Central nervous system (CNS) involvement is a known complication of adult T-cell leukaemia/lymphoma (ATL), but its clinical characteristics and incidence still remain unclear. This study characterized the clinical features and incidence of CNS involvement in patients with ATL (CNS-ATL). Overall, 213 patients diagnosed with aggressive ATL were retrospectively analysed at the Kagoshima University Hospital between 2002 and 2021. Of which, 28 (13.1%) developed CNS-ATL. Patients with CNS-ATL observed at ATL diagnosis were classified as acute (n = 21, 75%), lymphoma (n = 1, 3.6%) or chronic (n = 5, 17.9%); CNS-ATL observed post-ATL diagnosis comprised 10.2% (10/98) acute, 1.8% (1/54) lymphoma and 16.1% (5/31) chronic cases. Of the 28 patients, 11 (39.3%) had asymptomatic meningeal involvement detected at prophylactic intrathecal therapy, 10 (35.7%) exhibited neurological symptoms at ATL diagnosis, 4 developed symptomatic CNS involvement during induction therapy and 3 experienced CNS relapse post-treatment. Two-year overall survival of CNS-ATL was significantly lower than that of non-CNS-ATL, whereas 1-year cumulative incidence of CNS involvement post-ATL diagnosis was 12.3%. In conclusion, CNS involvement in ATL tends to occur early in the disease course and is associated with a poor prognosis, with a tendency for a higher incidence in acute-type than in lymphoma-type ATL.
