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

Radiotherapy is essential in cancer treatment, using ionizing radiation to generate free radicals in the irradiated tissue or to directly damage DNA. Despite comprehensive safety measures, healthy tissue is also irradiated, causing side effects like oral mucositis and dermatitis. Antioxidants, which are known for scavenging free radicals, may reduce these adverse effects, but their impact on radiotherapy efficacy remains unclear. The aim of this systematic review was to evaluate the influence of antioxidant supplementation on radiation-induced side effects, tumor outcome and quality of life. In April 2024, a systematic research was conducted searching five databases (Medline, CINAHL, EMBASE, Cochrane CENTRAL, PsycINFO) to find studies looking at the effect of antioxidant supplementation during radiotherapy on radiation-induced side effects and parameters of tumor outcome or survival. Antioxidants can mitigate radiation-induced side effects, with vitamins C and E showing positive effects on oral mucositis, xerostomia and cardiac function. Curcumin and EGCG improved symptoms such as mucositis, dermatitis and esophagitis, while glutathione-enhanced treatment compliance but did not provide significant protection against side effects. However, multiple studies indicate that the concurrent use of antioxidants during cancer treatment may impair tumor control, increase recurrence rates and reduce survival outcomes. Antioxidants may reduce radiation-induced side effects but could compromise treatment efficacy. Due to inconsistent evidence and potential risks, clinical recommendations are premature. Further high-quality research is needed.
