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

backgroundThe pattern of recurrence affects the clinical outcome in tumor patients. However, the clinical significance of lung metastasis as the primary recurrence site after resection in patients with pancreatic cancer remains unclear. This study aimed to clarify the clinical significance of the primary recurrence site in patients with pancreatic cancer, in terms of prognosis and clinicopathological features.

methodsThis retrospective cohort study included 220 patients with postoperative recurrence after pancreatectomy for pancreatic cancer and classified by primary site of recurrence. We focused on patients with lung metastasis as the primary recurrence and investigated its correlation with prognosis and clinicopathological factors.

resultsTwenty-four (11%) patients had lung metastasis as the primary recurrence. This recurrence pattern had the best prognosis among all recurrence patterns, including liver metastasis and local recurrence. Patients with lung metastasis as the primary recurrence had favorable overall survival and survival from the date of recurrence compared with patients with other primary recurrence sites in both univariate (P = 0.0008 and P = 0.0005) and multivariate analyses (P = 0.0051 and P = 0.0068). In terms of clinicopathological features of resected pancreatic tumors, lung metastasis as the primary recurrence was associated with lower tumor stage and histologic grade, and less vascular invasion and residual tumor volume than liver metastasis.

conclusionsPancreatic cancer patients with lung metastasis as the primary recurrence after pancreatectomy have a better prognosis than those with other recurrence patterns.
