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

objectivesThe purpose of this study was to compare approved first-line therapies for patients with multiple myeloma.

methodsA systematic literature search for phase III randomized controlled trials (RCTs) comparing first-line chemotherapies approved in Germany and recommended by guidelines at the time of study design was conducted. Random-effects meta-analysis (MA) was used for direct and the Bucher method for adjusted indirect treatment comparison.

resultsOne RCT comparing melphalan and prednisone plus bortezomib (VMP) vs. melphalan and prednisone (MP) and six RCTs comparing MP plus thalidomide (MPT) vs. MP were analysed. For MPT vs. MP, an individual patient data (IPD) MA was used for sensitivity analyses. VMP and MPT were superior to MP regarding efficacy endpoints (VMP vs. MP, overall survival (OS): hazard ratio (HR) 0.70, 95 % confidence interval (CI) 0.57-0.86; progression-free survival (PFS): HR 0.56, 0.39-0.79; complete response (CR), risk-ratio (RR) for non-response: 0.70, 0.65-0.75; MPT vs. MP, OS: HR 0.83, 0.66-1.03; PFS: HR 0.67, 0.56-0.81; CR, RR for non-response 0.92, 0.88-0.95); but had a higher risk of developing any grade 3-4 adverse events (AEs) (VMP vs. MP: RR 1.13, 1.06-1.20; MPT vs. MP: RR 2.06, 1.43-2.98). The indirect comparison of VMP vs. MPT via MP showed a statistically not significant advantage for VMP regarding survival outcomes (OS: HR 0.85, 0.63-1.14; PFS: HR 0.83, 0.56-1.23) and a significant advantage regarding CR (RR for non-response 0.76, 0.70-0.83) and AEs (RR 0.55, 0.38-0.80). Treatment comparisons using results of IPD MA yielded similar effect sizes.

conclusionsVMP and MPT seem more effective than MP, VMP was superior to MPT regarding response criteria and AEs. Our results may best be confirmed by a head-to-head trial of VMP vs. MPT.
