Survival of childhood and adolescent/young adult (AYA) cancer patients in Ireland during 1994-2013: comparisons by age.
Article in Irish journal of medical science, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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.
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
backgroundSome studies indicate that survival of adolescents and young adults (AYA) with cancer may be inferior to that of younger children with similar cancers, possibly related (in part) to differences in access to centralized or standardized treatment.
aimsThis study aims to evaluate differences in survival for AYA patients when compared with paediatric patients treated in Ireland over a 20-year time period.
methodsThis study compares relative survival for patients diagnosed in Ireland at ages 0-15 (paediatric group) and 16-24 (AYA group) during 1994-2013, followed to the end of 2014, for cancers defined by the International Classification of Childhood Cancer (ICCC) (Third Edition) group or subgroup. Five-year relative survival estimates, and excess hazard ratios (EHR) comparing excess mortality associated with a cancer diagnosis among AYA with that in the paediatric group, are presented. This research did not receive any specific grant from funding agencies in the public, commercial, or not-for-profit sectors.
resultsSignificantly higher excess mortality was found for AYA with leukaemias, lymphomas, astrocytomas, malignant bone tumours, and Ewing and related bone sarcomas, soft tissue sarcomas and 'other/unspecified' epithelial cancers, rhabdomyosarcomas, and 'other and unspecified' carcinomas. In contrast, lower excess mortality was found in the AYA group for all cancers and intracranial/intraspinal tumours, and for gliomas other than astrocytomas or ependymomas. Comparing 1994-2003 and 2004-2013 cohorts, age-related survival differences narrowed for lymphoid leukaemias, but widened for all cancers combined and intracranial/intraspinal tumours combined. Centralization of services varied depending upon cancer subtype, with leukaemias, CNS tumours and bone sarcomas most centralized. Within these, improvements in survival for leukaemias and CNS tumours have been seen for the AYA population.
conclusionsReasons for age-related survival differences, and differences in time-trend by age group, are not clear. The significant narrowing of survival differences by age in more recent years for lymphoid leukaemias reflects a more marked recent increase in survival among AYA. More work is required to explain and improve other age-related survival differences.
