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

Time to progression (TTP) is widely used as the endpoint in early-phase trials of advanced hepatocellular carcinoma (HCC). However, the relevance of using TTP as a surrogate marker for overall survival (OS) in pivotal trials remains uncertain. The PubMed database and ASCO Meeting Library were searched for reports of randomized controlled trials that investigated patients with advanced HCC, included data for both OS and TTP, and were launched between 2009 and 2016. The correlation between hazard ratios (HRs) for TTP and OS was determined using weighted linear regression. Correlations between median OS and TTP, and between median OS and postprogression survival (PPS), defined as the period obtained by subtracting the median TTP from the median OS, were also evaluated. The database search yielded 24 trials with 50 arms. Overall, TTP HR correlated with OS HR (
