Evaluation of Treatment Modalities for Radiation Therapy-Induced Trismus, Considering the Timing and Adherence to Progress in Mouth Opening and Oral Health-Related Quality of Life: A Systematic Review.
Review in Patient preference and adherence, 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
Purpose: To assess the effectiveness of treatment modalities for radiation-induced trismus in improving mouth opening (MO) and oral health-related quality of life (OHRQoL), with considering of treatment timing and patient adherence. Methods: Electronic databases (PubMed, Google Scholar, Scopus, EBSCOhost, and ScienceDirect) were searched for studies published between 2015 and 2025 using relevant Medical Subject Headings (MeSH) combined with Boolean operators, including "Treatment OR therapy AND trismus OR limited mouth opening AND radiation therapy OR radiotherapy AND head and neck neoplasm OR head and neck cancer" and "Timing OR starting time AND treatment OR exercise AND trismus OR limited mouth opening OR restricted mouth opening." After duplicate removal, titles, abstracts, and full texts were screened for eligibility. Results: The initial search identified 472,480 articles, of which 18 met the inclusion criteria after screening titles, abstracts, and full texts. Kruskal-Wallis analysis demonstrated significantly greater improvement in mouth opening when trismus treatment was initiated during or after radiotherapy compared to before radiotherapy (p = 0.020). The greatest improvement was observed with combined laser therapy and Therabite exercises, initiated concurrently with radiotherapy for 3 months with high adherence, resulting in a mean increase of 26.95 mm in MO and an improvement in OHRQoL. The second most effective modality was threaded tapered screw appliance (TTSA) therapy combined with low-level laser therapy (LLLT) administered post-radiotherapy for 6 weeks, yielding a 15 mm improvement with high adherence. Conclusion: The effectiveness of treatment for radiation-induced trismus is influenced by the therapeutic modality, timing of therapy initiation, and patient adherence, all of which contribute to improvements in MO and OHRQoL. Combination therapy modalities, particularly laser therapy combined with jaw movement devices, initiated during or after radiotherapy and supported by high patient adherence, optimize mouth opening and enhance OHR-QoL.
