1 · What the graph read from it

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.

2 · The registry

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

purposeCongenital cholesteatoma (CC) presents as a white pearl-like lesion behind a normal tympanic membrane (TM), without a history of otorrhea, infection, perforation or previous otologic surgery. Several recent studies provided new data improving this pathology characterization. The aim of this paper is to expand the knowledge about CC and to provide new insights on its pathogenesis.

methodsThe study consisted of two main research parts: (1) systematic review and meta-analysis; (2) medical literature review englobing anatomy, histology, embryology and congenital pathology of the ear.

resultsThe search strategy identified a total of 636 papers. Seventy retrospective studies were included. A total of 1497 cases were studied and the mean age was 6.58 years, with a male-female ratio of 3:1, 34% were asymptomatic, 26% had hearing loss and 2% had facial dysfunction/paralysis. The overall estimate for antero-superior quadrant involvement was 0.70 [95% confident interval (CI) 0.64-0.76], in the postero-superior quadrant was 0.60 (95% CI 0.52-0.69), in the antero-inferior quadrant was 0.32 (95% CI 0.23-0.41), in the postero-inferior quadrant was 0.38 (95% CI 0.29-0.47), in the attic was 0.53 (95% CI 0.43-0.63) and in the mastoid was 0.33 (95% CI 0.26-0.41). More advanced Potsic stages were present in older patients. The most likely inclusion place seems to be between the pars flaccida and the upper quadrants of the pars tensa.

conclusionsDuring the last decades, a substantial improvement in CC diagnosis and management had been achieved. The presented mechanism seems to explain most of middle ear CC.
