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

backgroundWe determined the minimum threshold (Tmin) of annual facility case volume to optimize outcomes for patients with resected perihilar cholangiocarcinoma.

methodsWe identified patients with localized perihilar cholangiocarcinoma who underwent resection within the National Cancer Database (2010-2017). We used marginal structural logistic regression models to estimate the average treatment effect of receiving care in facilities meeting/exceeding Tmin on 90-day mortality and other postoperative outcomes.

resultsA total of 2471 patients underwent resection for perihilar cholangiocarcinoma at 471 facilities. There was no effect of total hepatopancreatobiliary, surgical hepatopancreatobiliary, total hepatobiliary, surgical hepatobiliary, or total perihilar cholangiocarcinoma case volume on 90-day mortality. A Tmin of seven perihilar cholangiocarcinoma resections/year resulted in lower odds of 90-day mortality (IP-weighted OR = 0.49, 95% CI: 0.66-0.87). A total of two facilities met the Tmin. Patients receiving treatment at Tmin facilities had lower odds of length of stay ≥ 7 days (IP-weighted OR = 0.85, 95% CI: 0.75-0.97) and positive surgical resection margins (IP-weighted OR = 0.40, 95% CI: 0.47-0.55). Additionally, undergoing surgery at Tmin facilities resulted in higher (≥ 4 nodes) lymph node yields (IP-weighted OR = 1.94, 95% CI: 1.21-3.11) but no change in the odds of nodal positivity. There was no effect of undergoing surgery at Tmin facilities on 30-day mortality or re-admission.

conclusionsResection of perihilar cholangiocarcinoma is infrequently performed at a high number of facilities. A Tmin of ≥ 7 resections/year resulted in lower 90-day mortality and improved postoperative outcomes. Our data suggest that regionalization of care for patients with perihilar cholangiocarcinoma could potentially improve outcomes in the USA.
