Mastoid Surgery Does Not Normalize Tympanometric Middle Ear Pressure in Children With Cholesteatoma.

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
objectiveTo determine whether transcanal surgery without mastoidectomy, canal wall up (CWU), canal wall down (CWD), or CWU mastoid obliteration (MO) surgery for pediatric cholesteatoma has a more favorable effect on middle ear pressure (MEP) homeostasis.
methodsData from children having mastoid surgery for acquired cholesteatoma were collected prospectively. Tympanometric values of MEP were compared after transcanal, CWU, CWD, and MO surgery analyzing (i) a single measure per ear from last clinic visit, and (ii) linear mixed-effects modeling (LMEM) to control for multiple measures, surgeries, age, and cholesteatoma severity (EAONO-JOS stage).
results742 surgeries on 471 ears and 2382 tympanograms were completed. At last visit, (average age 15.6 years [6.0-19.3]), Type a tympanograms were present in 80/173 (46%) of transcanal surgeries, 64/132 (48%) CWU, 15/32 (47%) CWD, and 11/25 (44%) MO (Chi-square, p = 0.19), but 185/209 (89%) contralateral ears without cholesteatoma (Chi-square: p = 1.08 × 10
conclusionMEP after surgery for pediatric cholesteatoma is similar after transcanal, CWU, CWD, or MO surgery and remains lower than normal. Hypotheses that propose beneficial effects of these different surgical approaches on MEP homeostasis are not supported, so should not be used to influence choice of surgical approach.
