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

backgroundCentralization of pancreatic cancer surgery aims to improve postoperative outcomes. Consequently, patients with pancreatic cancer may undergo pancreatic surgery in an expert centre and adjuvant chemotherapy in a local hospital (network treatment). The aim of this study was to assess whether network treatment has an impact on time to chemotherapy, failure to complete adjuvant chemotherapy, and survival. Second, whether these parameters varied between pancreatic networks was studied.

methodsThis retrospective study included all patients diagnosed with non-metastatic pancreatic ductal adenocarcinoma who underwent pancreatic surgery and adjuvant chemotherapy, registered in the Netherlands Cancer Registry (2015-2020). Time to chemotherapy was defined as the time between surgery and the start of adjuvant chemotherapy. Completion of adjuvant chemotherapy was defined as the receipt of 12 cycles of FOLFIRINOX or six cycles of gemcitabine. Analysis was performed with linear mixed models and multilevel logistic regression models. Cox regression analyses were performed for survival.

resultsIn total, 1074 patients were included. Network treatment was observed in 468 patients (43.6 per cent) and was not associated with longer time to chemotherapy (0.77 days, standard error (s.e.) 1.14, P = 0.501), failure to complete adjuvant chemotherapy (odds ratio (OR) = 1.140, 95 per cent c.i. 0.86 to 1.52, P = 0.349), and overall survival (hazards ratio (HR) = 1.04, 95 per cent c.i. 0.88 to 1.22, P = 0.640). Significant variation between the networks was observed for time to chemotherapy (range 40.5-63 days, P < 0.0001) and completion of adjuvant chemotherapy (range 19-52 per cent, P = 0.030). Adjusted for case mix, time to chemotherapy significantly differed between networks.

conclusionIn this nationwide analysis, network treatment in patients with resected pancreatic cancer was not associated with longer time to chemotherapy, failure to complete adjuvant chemotherapy, and worse survival. Significant variation between pancreatic cancer networks was found for time to chemotherapy.
