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

purposeThe management of inferior vena cava (IVC) tumor thrombus in patients with renal cell carcinoma (RCC) is among the most challenging surgical procedures. We aimed to define a minimum annual caseload for sufficient expertise.

methodsWe identified all cases with RCC, nephrectomy, and IVC procedures in the Federal Statistical Office billing database (2006-2020). We defined annual hospital caseload categories as low (< 4 cases), medium (4-9 cases) and high (> 9 cases) volume. Logistic multivariate models identified mortality-related factors. In addition, we analyzed data on tumor stage distribution from German cancer registries.

resultsWe recorded 3,700 nephrectomies with IVC-tumor resection with stable annual case number of 247 mean. This correlated with a stable incidence of T3b/c RCC. Patient age was 66 ± 14 years. Of all cases, 56% occurred in low, 30% in medium, and 14% in high volume clinics without a significant trend towards centralization. The overall in-hospital mortality rate was 5.8% and the transfusion rate 72%. An annual caseload of 8 showed to be a significant cut-off for mortality with 6.2% at < 8 cases and 2.8% for > = 8 cases annually (p < 0.001). Multivariate analysis revealed patient age (OR 6.4 for octogenerians) ventilation time (OR 14.3 for > 24 h) and hospital caseload (OR 2.6) as the most important risk factors for in-hospital mortality.

conclusionOur results show a negative correlation of annual caseload and mortality for this procedure. A minimum number of 8 procedures per year seems reasonable for the successful management of IVC tumor thrombus with significantly lower mortality.
