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

Background: In pancreatic ductal adenocarcinoma (PDAC), only radical surgery improves long-term survival. We focused on surgical outcome after induction gemcitabine along with nab-paclitaxel (GnP) and subsequent chemoradiotherapy (CRT) with S-1 administration for unresectable locally advanced (UR-LA) PDAC. Methods: We retrospectively analyzed 144 patients with UR-LA PDAC between 2014 and 2020. The first-line regimen of induction chemotherapy was GnP for 125 of the 144 patients. Of the 125 patients who received GnP, 41 who underwent radical resection after additional preoperative CRT were enrolled. We evaluated the prognostic factors for this treatment strategy. Results: The median length of preoperative GnP was 8.8 months, and 30 (73%) patients had normalized CA19-9 levels. R0 resection was achieved in 36 (88%) patients. Postoperative major complications of ≥Clavien-Dindo grade IIIa developed in 16 (39%) patients. With a median follow-up of 35.2 months, 14 (34%) patients developed distant metastasis postoperatively. Using the Kaplan-Meier method, prognostic analysis of the 41 cases revealed the 3-y overall survival rate (OS) was 77.4% and the 5-y OS was 58.6%. In univariate analysis, length of preoperative GnP (≥8 months), CA19-9 normalization, and good nutritional status at operation (prognostic nutritional index ≥41.7) were significantly associated with favorable prognosis. Multivariate analysis revealed CA19-9 normalization (hazard ratio [HR] 0.23; Conclusion: For surgical outcome after induction GnP and subsequent CRT for UR-LA PDAC, CA19-9 normalization and maintenance of good nutritional status during treatment until surgery were important for prolonged prognosis.
