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

backgroundGlioblastoma multiforme is the most common and aggressive primary adult brain neoplasm. The current standard of care is maximal safe surgical resection, radiotherapy with concomitant temozolomide, followed by adjuvant temozolomide according to the Stupp protocol. Although the protocol is well adopted in high-income countries (HICs), little is known about its adoption in low- and middle-income countries (LMICs). The aim of this study is to describe a protocol design for a systematic review of published studies outlining the differences in GBM management between HICs and LMICs.

methodsA systematic review will be conducted. MedLine via Ovid, Embase and Global Index Medicus will be searched from inception to date in order to identify the relevant studies. Adult patients (>18 years) with histologically confirmed primary unifocal GBM will be included. Surgical and chemoradiation management of GBM tumours will be considered. Commentaries, original research, non-peer reviewed pieces, opinion pieces, editorials and case reports will be included.

resultsPrimary outcomes will include rates of complications, disability-adjusted life years (DALYs), prognosis, progression-free survival (PFS), overall survival (OS) as well as rate of care abandonment and delay. Secondary outcomes will include the presence of neuro-oncology subspecialty training programs. DISCUSSION: This systematic review will be the first to compare the current landscape of GBM management in HICs and LMICs, highlighting pertinent themes that may be used to optimise treatment in both financial brackets. SYSTEMATIC REVIEW REGISTRATION: The protocol has been registered on the International Prospective Register of Systematic Reviews (PROSPERO; registration number: CRD42020215843). HIGHLIGHTS: Glioblastoma multiforme (GBM) remains the most common primary adult cerebral neoplasm, with an age-adjusted incidence rate of 3.22 per 100,000 population and a 5-year survival rate of 6.8%Despite the well-evidenced efficacy of Stupp protocol, the implementation of this approach bears an institutional and individual financial burden that is particularly notable in low- and middle-income countries (LMICs)This systematic review will be the first to compare the current landscape of GBM management in HICs and LMICs, highlighting pertinent themes that may be used to optimise treatment in both financial brackets.
