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 dynamics of postoperative carcinoembryonic antigen (CEA) in pancreatic ductal adenocarcinoma (PDAC) patients have not been well assessed. This study investigated the correlation between postoperative CEA elevations and tumor recurrence.

methodsMedical records were retrospectively analyzed for 84 patients who received curative resection for PDAC from January 2019 to December 2020. Postoperative CEA levels were monitored for a minimum of 12 months. False-positive CEA elevation was defined as a CEA level exceeding 5 ng/mL without evidence of recurrence in imaging studies.

resultsOf the examined patients, 59 (70%) exhibited CEA > 5 ng/mL within the observation period. The sensitivity and specificity of elevated CEA levels for detecting recurrence were 84% and 41%, respectively. CEA elevations without tumor recurrence were observed in 27 patients, indicating a false-positive rate of 59%. More than half of these patients demonstrated peak CEA levels between 5 and 10 ng/mL, while only true-positive patients exhibited CEA levels exceeding 40.0 ng/mL.

conclusionCEA may rise in more than half of postoperative PDAC patients without recurrence. CEA alone is not a robust postoperative marker.
