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

backgroundCyclin-dependent kinase inhibitor 2A/B (CDKN2A/B) genes are frequently altered in acute lymphoblastic leukaemia (ALL) patients. The aim of this meta-analysis was to comprehensively assess the prognostic value of CDKN2A/B deletions in ALL patients.

methodsSystematic literature review was conducted in PubMed, Embase and Cochrane databases up to July 2018. Pooled hazard ratios (HRs) with 95% confidence intervals (CIs) were calculated with fixed-effects or random-effects models.

resultsA total of thirteen studies including 2857 patients were eligible for this meta-analysis. Combined HRs suggested that CDKN2A/B deletions were poor prognostic factors for both overall survival (OS) (HR = 2.15, 95% CI 1.82-2.54) and event-free survival (EFS)/disease-free survival (DFS)/relapse-free survival (RFS) (HR = 2.16, 95% CI 1.73-2.69). The adverse impact remained significant in both adult and paediatric ALL patients, and also in subgroups by ethnicity, ALL type, detection method of CDKN2A/B deletions, statistical method and endpoint.

conclusionsOur findings suggested that CDKN2A/B deletions were associated with poor prognosis independently in both adult and childhood ALL patients. Inclusion of CDKN2A/B status may further improve the risk stratification of ALL patients. Key Messages Although numerous studies have explored the prognostic significance of cyclin-dependent kinase inhibitor 2A/B (CDKN2A/B) deletions in acute lymphoblastic leukaemia (ALL) patients, the results remain conflicting. In this meta-analysis, we found that CDKN2A/B deletions were independent poor prognostic markers for both adult and paediatric ALL patients. Our findings justify the inclusion of CDKN2A/B status in the risk stratification of ALL patients.
