Article in Oncotarget, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05586256 (Ultra-hypofractionated Adjuvant Radiotherapy After Breast Conserving Surgery in Breast Cancer Patients), which is not on this map. Not yet cited in PubMed.

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.

Abstract

One third of patients with bladder cancer present with muscle invasive bladder cancer (MIBC) which has a poor prognosis. International guidelines for the management of MIBC recommend radical cystectomy or bladder-preserving treatment based on radical radiotherapy with a form of radiosensitisation. In the UK, both conventional fractionation with 64 Gy in 32 fractions and hypofractionation with 55 Gy in 20 fractions are standard of care options with the choice varying between centres. A meta-analysis of individual patients with locally advanced bladder cancer from two UK multicentre phase 3 trials was published recently. This study evaluated the non-inferiority of a hypofractionated schedule compared to a conventional regime. This analysis confirmed the non-inferiority of the hypofractionated regimen, and noted superior locoregional control. We discuss the relevance of these findings to current practice while considering the radiobiology of hypofractionation, the role of systemic therapies and radiosensitisation, as well as the socioeconomic benefits.
