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

backgroundThere is increasing interest in transplanting patients with hepatocellular carcinoma (HCC) with tumors greater than 5 cm (Milan criteria).

aimTo investigate possible prognostically-useful factors for liver transplantation in HCC patients with large tumors.

methodsIn this clinical study, 50 patients with HCC who were transplanted at our Liver Transplant Center between April 2006 and August 2019 and had tumors greater than 6 cm maximum diameter were retrospectively analyzed. Their survival and full clinical characteristics were examined, with respect to serum alpha-fetoprotein (AFP) and gamma glutamyl transpeptidase (GGT) levels. Kaplan-Meier survival estimates were used to determine overall survival and disease-free survival in these patients. The inclusion criterion was evidence of HCC. Exclusion criteria were the presence of macroscopic portal vein thrombosis or metastasis and a follow-up period of less than 90 d.

resultsUsing receiver operating characteristic curve (ROC) analysis, cutoff values of AFP 200 ng/mL and GGT 104 IU/L were identified and used in this study. Significantly longer overall survival (OS) and disease-free-survival (DFS) were found in patients who had lower values of either parameter, compared with higher values.  Even greater differences in survival were found when the 2 parameters were combined. Two tumor size bands were identified, in searching for the limits of this approach with larger tumors, namely 6-10 cm and > 10 cm. Combination parameters in the 6-10 cm band reflected 5-year OS of 76.2% in patients with low AFP plus low GGT

conclusionSerum levels of AFP and GGT, both alone and combined, represent a simple prognostic identifier in patients with large HCCs undergoing liver transplant-ation.
