Effect of curcumin intervention on radiation-induced injury: a GRADE-based systematic review and meta-analysis.
Synthesis in BMC cancer, 2026. 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
backgroundRadiation-induced injury (RII) is a common condition among patients receiving radiation therapy which affects the quality of life and clinical outcomes in cancer patients. Curcumin has shown promising therapeutic potential in the ameliorating RII through its radioprotective, anti-inflammatory and antioxidant properties. However, the findings across studies remain inconsistent.
methodsA comprehensive systematic search of PubMed, Web of Science, Embase, Cochrane Library, CNKI, Wanfang, and VIP was conducted from inception to 2 July 2025. Risk of bias was assessed using the Cochrane RoB 2.0 tool, and certainty of evidence was evaluated using GRADE approach.
resultsBased on finding, curcumin significantly reduced the incidence of severe RII (RR: 0.58, 95% CI: 0.46, 0.74; P < 0.001), the score of radiation injury severity (SMD: -0.90, 95% CI: -1.25, -0.55; P < 0.001), score of pain using NRS (SMD: -7.56, 95% CI: -9.47, -5.65; P < 0.001) and VAS (SMD: -1.53, 95% CI: -2.52, -0.54; P = 0.002) and weight (SMD: -0.69, 95% CI: -1.25, -0.13; P = 0.015). However, curcumin was not associated with the incidence of overall RII (RR: 0.98, 95% CI: 0.95, 1.01; P = 0.259).
conclusionThe present systematic review and meta-analysis indicated that curcumin may exert promising effects in mitigating RII. It has been shown that patients with RII may benefit from curcumin treatment through reduced incidence of severe RII and score of severity and adverse events. Nevertheless, well-designed studies across multiple populations with rigorous methodologies and optimized dose regimens are warranted to establish firm conclusions.
