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

backgroundMost patients with hepatocellular carcinoma (HCC) are ≥ 65 years old at diagnosis and ~ 20% present with disease amenable to curative intent surgical therapy. The aim of this study was to examine whether treatment, the demographic variables, and clinical factors could predict 5-year survival among HCC patients.

methodsWe included patients, 66 years or older, diagnosed with a first primary HCC from 1994 through 2007 in the SEER-Medicare database, and followed up until death or 31 December 2012. Curative intent treatment was defined as liver transplantation, surgery resection, or ablation. We estimated odds ratios (OR) and 95% confidence intervals (CI) for associations with 5-year survival using logistic regression.

resultsWe identified 10,826 patients with HCC with mean age 75.3 (standard deviation, 6.4) years. Most were male (62.2%) and non-Hispanic white (59.7%). Overall, only 8.1% of patients were alive 5 years post-HCC diagnosis date. Among all patients that survived ≥ 5 years, 69.8% received potentially curative treatment. Conversely, patients who received potentially curative treatment represented only 15.7% of patients who survived < 5 years. Curative intent treatment was the strongest predictor for surviving ≥ 5 years (vs. none/palliative treatment; adjusted OR 8.12, 95% CI 6.90-9.64). While stage at diagnosis and comorbidities were also independently associated with ≥ 5-year survival in HCC patients, these factors did not improve discrimination between short- and long-term survivors.

conclusionsCurative intent treatment was the strongest predictor for survival ≥ 5 years among HCC patients. Given the limited availability of liver transplant and limited eligibility for surgical resection, finding curative intent HCC therapies remain critically important.
