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.
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: Chemotherapy reportedly affects the patency of self-expandable metal stents (SEMSs) in patients with cancer. However, knowledge regarding the association between SEMS patency and progression-free survival (PFS) remains limited. This study aimed to assess PFS and SEMS patency in patients with advanced pancreatic cancer. Methods: Between January 2012 and June 2021, 74 patients with locally advanced or metastatic pancreatic cancer (MPC) were enrolled in the study. Patients received gemcitabine plus nab-paclitaxel (GnP) or fluorouracil, leucovorin, oxaliplatin, and irinotecan (FOLFIRINOX) as initial chemotherapy and SEMS within 1 month before or after the initial chemotherapy. Longer PFS was defined as PFS ≥7 months. Results: This study enrolled 38 male patients (51.4%); the mean age was 66.2 [95% confidence interval (CI), 63.7-68.6] years. Of the patients, 46 (62.2%) had MPC and 58 (78.4%) received FOLFIRINOX as the initial chemotherapy. Of the patients, 61 (82.4%) underwent endoscopic SEMS insertion. The median stent patency and PFS were 6.9 [interquartile range (IQR), 4.5-12.9] and 6.4 (IQR, 4.2-12.5) months, respectively; the median overall survival (OS) was 10.5 (IQR, 6.7-16.5) months. Of the clinical parameters assessed using multivariate analysis, shorter PFS [PFS <7 months; hazard ratio (HR), 2.117; 95% CI, 1.020-4.393; P=0.044] and metastatic cancer (HR, 2.414; 95% CI, 1.159-5.018; P=0.019) were found to be associated with shorter SEMS patency. The median SEMS patency in patients with longer PFS and those with shorter PFS was 14.3 and 7.0 months (P=0.012), respectively, and that in patients with locally advanced cancer and those with metastatic cancer was 16.7 and 7.0 months (P=0.006), respectively. The coefficient of determination between stent patency and PFS was 0.624. Conclusions: SEMS patency may be associated with PFS in patients with advanced pancreatic cancer who receive GnP or FOLFIRINOX.
