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 assess the correlation between recurrence-free survival (RFS) and overall survival (OS) in the hepatobiliary-pancreatic (HBP) surgical setting to validate RFS as a surrogate endpoint.

backgroundReliable surrogate endpoints for OS are still limited in the field of HBP surgery.

methodsWe analyzed patients who underwent curative resection for HBP disease [986 patients with pancreatic ductal adenocarcinoma (PDAC), 1168 with biliary tract cancer (BTC), 1043 with hepatocellular carcinoma, and 1071 with colorectal liver metastasis] from September 2002 to June 2022. We also conducted meta-analyses of randomized controlled trials of neoadjuvant or adjuvant therapy to validate the surrogacy in PDAC and BTC.

resultsCorrelation coefficients between RFS and OS were low for hepatocellular carcinoma ( p = 0.67) and colorectal liver metastasis ( p = 0.53) but strong for PDAC ( p = 0.80) and BTC ( p = 0.75). In a landmark analysis, the concordance rates between survival or death at 5 years postoperatively and the presence or absence of recurrence at each time point (1, 2, 3, and 4 years) were 50%, 70%, 74%, and 77% for PDAC and 54%, 67%, 73%, and 78% for BTC, respectively, both increasing and reaching a plateau at 3 years. In a meta-analysis, the correlation coefficients for the RFS hazard ratio and OS hazard ratio in PDAC and BTC were p = 0.88 ( P < 0.001) and p = 0.87 ( P < 0.001), respectively.

conclusionsThree-year RFS can be a reliable surrogate endpoint for OS in clinical trials of neoadjuvant or adjuvant therapy for PDAC and BTC.
