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
backgroundThe German Society for General and Visceral Surgery (DGAV) offers surgical departments certification as a specialist center for surgical treatment of liver diseases. Annual minimum case volumes have been defined for which, however, no empirical sources are available.
objectiveThis study examined the defined hospital volume requirements in the DGAV certification regulations for the field of surgical treatment of liver diseases with respect to in-hospital mortality.
methodsBased on the nationwide German hospital billing data (diagnosis-related groups, DRG statistics), the institutions were classified according to the criteria (minimum number of cases and TV30 criterion) of the DGAV certification regulations and the hospital mortality was compared. In addition, the relationship between the annual procedure volumes of institutes and in-hospital mortality was examined separately for the various types of interventions (interventions, anatomical liver resections, resection of more than three segments, resection of the fork of the hepatic duct).
resultsHospitals that met the requirements for higher certification levels had a higher hospital mortality (competence centers 3.03%, 95% confidence interval, CI: 2.24; 3.65, reference centers 4.26%, 95% CI: 3.28; 5.25, centers of excellence 6.13%, 95% CI: 5.56; 6.70). The separate evaluation of the types of intervention resulted in different case number limits with respect to the relationship between procedure volume and hospital mortality, above which hospital mortality is significantly lower than that defined in the DGAV certification.
conclusionThe findings indicate that the existing certification criteria for the minimum number of cases and the TV30 criterion should be readjusted.
