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
Diseases of adenoids are commonly observed in children. It indirectly leads to pathology in the middle ear cleft. It has been demonstrated both by radiological techniques and middle ear pressure studies that adenoids can and do obstruct the Eustachian Tube. The Adenoid-Nasopharyngeal Ratio (ANR), can offer a simple arithmetic measure of nasopharyngeal obstruction. Coupled with tympanometry, it also predicts the degree to which the middle ear is affected. Multicentric study done at two centres in India. 230 patients were studied. Children were in the age group of 5-14 years. The nasopharyngeal and adenoid dimensions were measured separately using the Fujioka method. The adenoid-nasopharyngeal ratio was derived by the arithmetic method. All patients were also subjected to tympanometry. ANR decreased from 0.728 to 0.663 with an increase in age from 5 to 12 years. ANR between 0.701-0.800 had maximum number of Type B (140) and Type C (71) Tympanogram whereas between 0.801 and 0.900, all Tympanogram were found to be of Type B or Type C with none belonging to Type A. Using ANR and Tympanometry, the effects of the adenoids on the middle ear can be quantified indirectly. Both these modalities are easily available, economical, safe and can be performed at the Out Patient Level. This aids in timely and appropriate management thus preventing discomforting symptoms caused by the adenoids locally and also the morbidity caused to the middle ear in the long term.
