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

backgroundAlthough liver transplantation may potentially cure hepatocellular carcinoma (HCC), the risk of HCC recurrence is 8%-20% at five years post-transplant. Pre-transplant alpha-fetoprotein (AFP) is a predictor of HCC recurrence, but it is unknown if pre-transplant AFP also predicts survival in patients with recurrence.

methodsWe performed a retrospective cohort study using the United Network for Organ Sharing (UNOS) database between 2002 and 2016. We identified adult transplant recipients with HCC recurrence after liver transplantation for HCC and used Cox regression to compare patient survival among different maximum pre-transplant AFP levels.

resultsThe cohort (N = 1164) was primarily male, white, and with hepatitis C liver disease. The median time to HCC recurrence was 11.6 months (interquartile range 6.1-26.3). In Cox regression analysis, increasing pre-transplant AFP was associated with poorer survival when adjusting for age, pre-transplant model for end-stage liver disease (MELD), and time to HCC recurrence. For example, patients with pre-transplant AFP ≥500ng/mL had a 1.6-fold higher risk of death versus those with AFP ≤20ng/mL (P < 0.001).

conclusionPre-transplant AFP is independently associated with survival in patients with HCC recurrence. These findings further contextualize the importance of pre-transplant AFP in liver transplantation and may improve prognostication for patients with HCC recurrence.
