A Systematic Review of Phase II/III Trials of Hypofractionated versus Conventionally Fractionated Radiation Therapy in Stage III Non-Small Cell Lung Cancer Patients.
Review in Cancers, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionThis systematic review evaluated whether curative intent hypofractionated radiation therapy improved survival (primary endpoint) as compared to standard conventionally fractionated radiation therapy for stage III non-small cell lung cancer (NSCLC) patients. Toxicity was also examined as a secondary endpoint.
methodsElectronic bibliographic databases were searched from 1 January 1990 to 31 March 2024. Phase II and phase III trials were included to assess survival (primary outcome) and toxicity (secondary outcome) for newly diagnosed stage III NSCLC patients.
resultsEight phase II trials (
conclusionsThere is no level 1 evidence to date that suggests that any hypofractionated regimen (dose escalated or not) improves survival as compared to conventionally fractionated radiation. The published phase III trials have been powered for superiority (not equivalence) for the hypofractionated arm. Toxicity with hypofractionated regimens may be similar to conventionally fractionated regimens when normal tissue radiotherapy constraints are kept within tolerance limits. It is unclear how the use of systemic therapy may negatively affect radiation toxicity with hypofractionated radiation therapy.
