Preventive measures for the progression of dysphagia in patients with cancer of head and neck subjected to radiotherapy: a systematic review with meta-analysis.
Synthesis in CoDAS, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
purposeTo identify the effects of prophylactic, non-pharmacological measures on the progression of dysphagia in patients with head and neck cancer undergoing radiotherapy. RESEARCH STRATEGIES: The search was performed in Medline (via PubMed), Scopus, and Embase databases, as well as in the gray literature. SELECTION CRITERIA: Randomized clinical trials were included, with adult patients (≥ 18 years old) and diagnosed with head and neck cancer, treated with radiotherapy (with or without surgery and chemotherapy), and submitted to non-pharmacological protocols for the prevention of dysphagia. DATA ANALYSIS: The risk of bias was assessed using the PEDRO scale and the overall quality of evidence was assessed using the GRADE instrument.
resultsFour studies were considered eligible, and of these, two were included in the meta-analysis. The result favored the intervention group, with a mean difference of 1.27 [95% CI: 0.74 to 1.80]. There was low heterogeneity and the mean score for risk of bias was 7.5 out of 11 points. The lack of detail in the care with selection, performance, detection, attrition, and reporting biases contributed to the judgment of the quality of the evidence, considered low.
conclusionProphylactic measures to contain dysphagia can promote important benefits on the oral intake of patients with head and neck cancer when compared to those who did not undergo such a therapeutic measure during radiotherapy.
