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

backgroundIn patients with pancreatic or periampullary tumor, staging laparoscopy (SL) can detect metastases that are occult on computed tomography (CT), thereby precluding nontherapeutic laparotomy. Routine SL is not advocated, but some studies suggest its selective use. The aim of this study was to identify patients at risk for metastasis in whom SL could be beneficial.

methodsA consecutive series of patients who underwent laparotomy for a suspected pancreatic or periampullary tumor were analyzed. We included patients with a suspected resectable solid lesion and a recent high-quality CT scan. Patients with and without an intraoperatively encountered metastasis were compared. Regression analysis was performed to examine the association between various predictors and metastasis.

resultsData from 385 patients (mean age 63, 41% women) were analyzed. Distant metastasis was encountered in 79 patients (21%). Logistic regression analysis revealed the following key predictors for metastasis: tumor size on CT scan [odds ratio (OR) 1.43, 95% confidence interval (CI) 1.16-1.76 per millimeter increase], weight loss (OR 1.28, 95% CI 1.01-1.63 per doubling the kilograms), and history of jaundice (OR 2.36, 95% CI 0.79-7.06). In patients with a tumor ≥3 cm and severe weight loss (≥10 kg) and in patients with a tumor ≥4 cm and moderate weight loss (≥5 kg), the proportion of patients with metastasis was >40%.

conclusionsIn patients with a suspected pancreatic or periampullary tumor, the tumor size, weight loss, and jaundice are key predictors of metastasis at exploration. SL might be beneficial in patients with a tumor ≥3 cm and severe weight loss and in those with a tumor ≥4 cm and moderate weight loss.
