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

purposeRadiotherapy-induced trismus is present in up to 40% of patients treated radiotherapeutically for head and neck cancer (HNC) and impacts health-related quality of life (HRQL) negatively. This prospective study aimed to investigate the development of trismus and its influence on HRQL and trismus-related symptoms in HNC patients for up to 5 years post-radiotherapy completion as no such follow-up studies exist.

methodsPatients (n = 211) were followed prospectively from pre-radiotherapy to 12 and 60 months post-radiotherapy. At each follow-up, maximum interincisal opening (MIO) was measured, and patients filled in the European Organization for Treatment of Cancer Quality-of-Life Questionnaire Core-30 (EORTC QLQ-C30), Head and Neck-35 (EORTC QLQ-HN35), and Gothenburg Trismus Questionnaire (GTQ). Trismus was defined as an MIO ≤ 35 mm.

resultsAt 1 year post-radiotherapy, a total of 27% met the trismus criterion, and at 5 years post-radiotherapy, the corresponding figure was 28%. Patients in the trismus group scored significantly worse compared to the patients without trismus on 8/15 domains at 1 year post-radiotherapy on EORTC QLQ-C30, further worsening in 11/15 domains at 5 years post-radiotherapy. Similar results were found for EORTC QLQ-HN35. Patients with trismus reported more trismus-related symptoms according to the GTQ at both timepoints compared to those without trismus.

conclusionThis study highlights that HNC patients suffering from radiotherapy-induced trismus report poorer HRQL and more trismus-specific symptoms compared to patients without trismus. These differences persist and increase up to at least 5 years following treatment completion. Hence, our results highlight that radiotherapy-induced trismus affects long-term HRQL, jaw symptoms, and pain, further stressing the need for early and structured intervention.
