PORP vs. TORP: a meta-analysis.
Synthesis in European archives of oto-rhino-laryngology : official journal of the European Federation of Oto-Rhino-Laryngological Societies (EUFOS) : affiliated with the German Society for Oto-Rhino-Laryngology - Head and Neck Surgery, 2013.

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
After the surgical procedure of ossicular chain reconstruction, the effectiveness and/or stability of partial ossicular replacement prosthesis (PORP) or total ossicular replacement prosthesis (TORP) were systematically compared and evaluated using meta-analysis. A total of 40 eligible investigations with 4,311 subjects were included in our study. There was a significant difference in the effectiveness of the reconstruction of the ossicular chain between PORP and TORP; the data showed a combined risk ratio (RR) of 1.28 (95 % CI 1.17-1.41, p < 0.00001), but no notable difference was obtained in staged procedures subgroup and cholesteatoma subgroup, with a combined RR of 1.13 (95 % CI 0.60-2.11, p = 0.70) in staged procedures subgroup and RR of 2.60 (95 % CI 0.20-36.21, p = 0.59 in cholesteatoma subgroup). There was a statistically significant difference in the stability of the prostheses in long-term follow-up, with a combined RR of 0.37 (95 % CI 0.16-0.85, p = 0.02), but no significant difference was observed in the total sample, with a combined RR of 0.64 (95 % CI 0.40-1.03, p = 0.06). Our overall results suggest that the effectiveness of PORP was higher than TORP, except within staged procedures subgroup and cholesteatoma subgroup. In addition, the stability of PORP was significantly superior to TORP in long-term follow-ups, but no significant effect was detected in the general study.
