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.

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.

Abstract

backgroundTo correlate between signal parameters using dynamic contrast-enhanced magnetic resonance imaging (DCEMRI) and outcomes of hepatocellular carcinoma (HCC) receiving radiotherapy with or without concomitant thalidomide.

methodsDCEMRI was performed in advanced HCC patients undergoing radiotherapy with or without concomitant thalidomide. Initial first-pass enhancement slopes (slope) and peak enhancement ratios (peak) were measured over an operator-defined region of interest over tumor and non-tumor liver parenchyma. The perfusion parameters were correlated with clinical outcomes. The study was registered with ClinicalTrials.gov. (identifier NCT00155272).

resultsForty-three patients were evaluable. There were 18 partial responses (PRs), 5 minimal responses (MRs), 17 stable diseases (SDs), and 3 progressive diseases (PDs). Baseline perfusion parameters as well as slope at 14 days of radiotherapy were higher in patients with PR or MR compared to SD or PD (0.81 ± 0.29 vs. 0.49 ± 0.34, p < 0.01; 0.39 ± 0.15 vs. 0.28 ± 0.16, p = 0.02; 0.97 ± 0.38 vs. 0.46 ± 0.26, p < 0.01; respectively). Multivariate analysis revealed perfusion parameters over liver parenchyma, but not over tumor, and independently predicted progression-free and overall survival (182 ± 33 vs. 105 ± 26 days, p = 0.01; 397 ± 111 vs. 233 ± 19 days, p = 0.001 respectively). For 22 patients receiving concomitant thalidomide, the perfusion parameters were not significantly different from those receiving radiotherapy alone.

conclusionsSignal parameters of DCEMRI over tumor and liver parenchyma correlated with tumor response and survival, respectively, in HCC patients receiving radiotherapy.
