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

backgroundTo assess trends in the distribution of patients for radical prostatectomy in Germany from 2006 to 2013 and the impact of robotic surgery on annual caseloads. We hypothesized that the advent of robotics and the establishment of certified prostate cancer centers caused centralization in the German radical prostatectomy market.

methodsUsing remote data processing we analyzed the nationwide German billing data from 2006 to 2013. We supplemented this database with additional hospital characteristics like the prostate cancer center certification status. Inclusion criteria were a prostate cancer diagnosis combined with radical prostatectomy. Hospitals with certification or a surgical robot in 2009 were defined as 'early' group. Linear covariant-analytic models were applied to describe trends over time.

resultsAnnual radical prostatectomy numbers declined from 28 374 (2006) to 21 850 (2013). High-volume hospitals (⩾100 cases) decreased from 87 (22.0%) in 2006 to 43 (10.4%) in 2013. Low-volume hospitals (<50 cases) increased from 193 (48.7%) to 280 (67.4%). Mean radical prostatectomy caseloads of hospitals with early vs without certification declined from 155 to 130 vs 77 to 39 (P=0.021 for trend comparison). Early robotic hospitals maintained their volume >200 cases per year contrary to the overall trend (P<0.001 for trend comparison). A multivariate model for caseload numbers of 2013 indicated a robotic system to be the most important factor for higher caseloads (multiplication factor 7.3; 95% confidence interval: 6.6-8.0). A prostate cancer center certification (multiplication factor 1.6; 95% confidence interval: 1.50-1.59) had a much smaller impact.

conclusionsWe found decentralization of radical prostatectomy in Germany. The driving force for this development might consist in the overall decline of radical prostatectomy numbers. The most important factor for achieving higher caseloads was the presence of a robotic system. In order to optimize outcomes of radical prostatectomy additional health policy measures might be necessary.
