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

purposeTo assess the efficacy of pemetrexed plus platinum doublet chemotherapy as first-line treatment for advanced nonsquamous non-small-cell lung cancer (NSCLC) through a trial-level meta-analysis.

methodsTrials published between 1990 and 2015 were identified by an electronic search of public databases (Medline, Embase, and Cochrane Library). All clinical studies were independently identified by two authors. Demographic data, treatment regimens, objective response rate (ORR), progression-free survival (PFS), and overall survival (OS) were extracted and analyzed using comprehensive meta-analysis software (version 2.0).

resultsA total of 2,551 patients with advanced nonsquamous NSCLC from ten trials were included for analysis: 1,565 patients were treated with pemetrexed plus platinum doublet chemotherapy and 986 with platinum plus other first-line chemotherapy. Pooled ORR for pemetrexed plus platinum chemotherapy was 37.8% (95% confidence interval [CI]: 31.7%-44.3%), with median PFS and OS of 5.7 and 16.05 months, respectively. When compared to other platinum-based doublet chemotherapies, the use of pemetrexed plus platinum chemotherapy significantly improved OS (hazard ratio [HR] =0.86, 95% CI: 0.77-0.97, P=0.01) but not PFS (HR =0.90, 95% CI: 0.80-1.01, P=0.084) in advanced nonsquamous NSCLC patients.

conclusionPemetrexed plus platinum doublet regimen is an efficacious treatment for advanced nonsquamous NSCLC patients. Our findings support the use of pemetrexed plus platinum doublet regimen as first-line treatment in advanced nonsquamous NSCLC patients because of its potential survival benefits.
