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

The availability of oral direct-acting antivirals has altered the hepatitis C virus (HCV) treatment paradigm for both pre-liver transplant (LT) and post-LT patients. There is a perceived trade-off between pre-LT versus post-LT treatment of HCV-treatment may improve liver function but potentially decrease the likelihood of a necessary LT. Our objective was to identify LT-eligible patients with decompensated cirrhosis who would benefit (and not benefit) from pre-LT treatment based on their Model for End-Stage Liver Disease (MELD) scores. We simulated a virtual trial comparing long-term outcomes of pre-LT versus post-LT HCV treatment with oral direct-acting antivirals for patients with MELD scores between 10 and 40. We developed a Markov-based microsimulation model, which simulated the life course of patients on the transplant waiting list and after LT. Simulation of LT integrated data from recent trials of oral direct-acting antivirals (SOLAR 1 and 2), the United Network for Organ Sharing (UNOS), and other studies. The outcomes of the model included life expectancy, 1-year and 5-year patient survival, and mortality. Model-predicted patient survival was validated with UNOS data. We found that, at the national level, treating HCV before LT increased life expectancy if MELD was ≤27 but could decrease life expectancy at higher MELD scores. Depending on the UNOS region, the threshold MELD score to treat HCV pre-LT varied between 23 and 27 and was lower for UNOS regions 3, 10, and 11 and higher for regions 1, 2, 4, 5, 8, and 9. Sensitivity analysis showed that the thresholds were stable.

conclusionOur findings suggest that the optimal MELD threshold below which decompensated cirrhosis patients should receive HCV treatment while awaiting LT is between 23 and 27, depending on the UNOS region. (Hepatology 2017;65:777-788).
