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

objectiveTo characterize associations between carbohydrate antigen 19-9 (CA19-9) dynamics during neoadjuvant therapy (NT) and survival for patients with pancreatic ductal adenocarcinoma (PDAC).

backgroundAlthough normalization of CA19-9 during NT is associated with improved outcomes following PDAC resection, we hypothesize that CA19-9 dynamics during NT can improve prognostication.

methodsCharacteristics for patients with PDAC undergoing NT (July 2011-October 2018) with ≥3 CA19-9 results (bilirubin<2mg/dL) were collected and grouped by CA19-9 dynamics. Nonproducers (<1 U/ml) were excluded, and normal was ≤35 U/ml. Postresection survival was compared among groups.

resultsOf 431 patients, 166 had eligible CA19-9 values. Median baseline CA19-9 was 98 U/ml. Overall 2-year postresection recurrence-free survival (RFS) and overall survival (OS) were 37% and 63%, respectively. Patients with normalization (53%) had improved 2-year RFS (47% vs. 28%, P = 0.01) and OS (75% vs. 49%, P = 0.01). CA19-9 dynamics during NT were analyzed by shape, direction, and normalization creating response types ("A-B-C-D-E"). Type A was "Always" decreasing to normalization, B "Bidirectional" with eventual normalization, C "Consistently" normal, D any "Decrease" without normalization, and E "Elevating" without normalization. Types A and B responses were associated with the longest postresection 2-year RFS (51% and 56%) and OS (75% and 92%, respectively) whereas Types D and E had the worst outcomes. After adjusting for node-positivity, perineural invasion, and margin-positivity, CA19-9 response types were independently associated with both RFS and OS, and predicted outcomes are better than CA19-9 normalization alone (likelihood ratio test RFS P < 0.001, OS P = 0.01).

conclusionsThis novel A-B-C-D-E classification of CA19-9 dynamics during NT was associated with postresection outcomes more precisely than CA19-9 normalization alone.
