Squamous cell carcinoma of the posterior pharyngeal wall: A comparative analysis of oropharyngeal origin versus hypopharyngeal origin.
Article in The Journal of laryngology and otology, 2024. 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
backgroundThe posterior pharyngeal wall is an anatomical subsite of both the oropharynx and hypopharynx. The treatment outcomes of squamous cell carcinoma (SCC) of these sites are generally published together, which makes the interpretation of data challenging. The aim of this analysis was to determine if there is any difference in the treatment outcomes of these two rare disease entities. MATERIALS AND
methodsRetrospetive analysis showed that the posterior pharyngeal wall was the primary subsite in 17 patients (1.65 per cent) out of 1031 patients with oropharyngeal SCC, and in 23 patients (11.73 per cent) out of 196 patients with hypopharyngeal SCC.
resultsThe five-year overall survival was 45 per cent for oropharyngeal origin and 53 per cent for hypopharyngeal origin patients. There was no significant difference in survival and locoregional control between these two groups of patients.
conclusionSquamous cell carcinoma of the posterior pharyngeal wall is a rare entity, which in our series represents 1.65 per cent of oropharyngeal cases and 11.73 per cent of hypopharyngeal tumours. There was no difference in treatment outcomes between the two groups.
