[Tonsil surgery: impact of the mouth gag on pharyngeal diameter].
Article in HNO, 2018. 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
backgroundPhoto documentation of hypertrophic tonsils is requested by some insurance companies to justify reimbursement of tonsillotomy. In 2017, a standardized photo documentation was introduced in tonsillotomy patients to verify the indication and effectiveness of the procedure.
objectiveUsing the archived photo documentation, this study aimed to evaluate the impact of two different positions of the mouth gag on the oropharyngeal airway. MATERIALS AND
methodsPictures were taken through the operating microscope after insertion of the mouth gag but without suspension (D1), after suspension before tonsillotomy (D2), and after resection of tonsillar tissue with the mouth gag under tension (D3). For each picture, a 10-mm scale from a single-use paper ruler was placed on the uvula. For this retrospective study, the patient's images were inserted into PowerPoint slides. Distances were measured with the use of an inserted rectangular grid.
resultsThe files of 149 patients undergoing tonsillotomy in a 6-month period were eligible for evaluation. Gender was balanced. The youngest patient was 16 months, the oldest patient 48 years old (mean: 6.95 years; median: 5 years). In all patients, tension of the mouth gag had significantly widened the oropharyngeal diameter (p < 0.001), making the tonsils appear smaller.
conclusionSuspension of the mouth gag results in a significant relative "downsizing" of the tonsils due to expansion of the oropharynx. Intraoperative photo documentation should also be performed without suspension of the mouth gag. Further studies may clarify whether stretching of the oropharynx has an impact on the distance between the tonsils and surrounding greater arteries.
