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
purposeHypernasality is a speech disorder that is frequently associated with various pathological conditions. However, its precise prevalence following adenoidectomy remains unclear. This study aimed to investigate the possible relation between velopharyngeal valve (VPV) closure patterns and the development of hypernasality following adenoidectomy.
methodsA prospective observational study was conducted on 100 children, aged 6-12 years, with adenoid hypertrophy who underwent total adenoidectomy after nasoendoscopic evaluation of velopharyngeal valve function. All participants were evaluated for postoperative hypernasality at 2 weeks and monthly up to 3 months.
resultsPreoperatively, all patients had good intelligibility of speech, 85% of cases had normal resonance, while 15% had a mild degree of hyponasality. Nasofibroscopic examination showed incomplete adenoid closure, adequate palatal length and mobility, and complete velopharyngeal valve closure in all subjects. Regarding velopharyngeal valve closure pattern, 65% of patients exhibited a coronal pattern and 35% a circular pattern. Postoperatively, only 5% of patients developed mild transient hypernasality at the two-week follow-up, while 95% maintained normal resonance. By the one-month assessment, all patients had achieved normal resonance.
conclusionsThere was no significant association between VPV closure patterns and the development of postoperative hypernasality. Meticulous preoperative assessment of VPV function can effectively minimize the risk of post-adenoidectomy hypernasality.
