Heterologous Materials Are Really Better than Autologous in Tympanoplasty Mastoid Obliteration? A Systematic Review with Meta-Analysis.

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
The aim is to analyze Literature concerning mastoid obliteration in adults with either autologous or heterologous grafts in the last 10 years. Data Source: Databases such as NIH PubMed, Bookshelf, NLM Catalog, Cochrane Library, and Embase were consulted. Thirty-seven studies were selected (22 concerning autologous materials, 15 about heterologous ones). Only studies with more than 12 months of follow-up were considered. A statistical analysis with random-effects models was performed to allow the true effect sizes to differ from study to study. The present literature review and meta-analysis does not allow to establish the supremacy of one technique over the other, but underlines the advantages of each reconstructive choice and the importance of mastoid obliteration in cholesteatoma surgery. The total number of obliterated ears was 2882. Overall otorrhea rate was 5% (5.2% for heterologous grafts; 4.9% for autologous materials; P < .05). Recurrent and residual cholesteatoma rate was 4.5% (3.4% in heterologous materials; 5.2% in autologous grafts; P < .05). Recurrent cholesteatoma rate was 1.8% (1.6% when using heterologous grafts, 1.9% with autologous; P < .05). Residual cholesteatoma rate was 1.5% (1.6% with heterologous materials, 1.5% with autologous; P < .05). TM (tympanic membrane) retraction pockets rate was 5.3% (3.6% with heterologous materials; P >.05; 7% with autologous materials; P < .05). TM perforations rate was 2.9% (4.3% with heterologous materials, 2.5% with autologous; P < .05). Infection rate was 2.3% (2.3% with heterologous materials, 2.2% with autologous; P < .05). Heterologous materials are associated with significantly lower rates of recurrent and residual cholesteatoma and retraction pockets development, although they are associated with higher rates of otorrhea and TM perforation.
