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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Although epidermal growth factor receptor (EGFR) monoclonal antibodies (mAbs) have been proved synergistic effect when combined with cytotoxic agents for advanced nonsmall cell lung cancer (NSCLC), the results of relevant clinical trials remain controversial. The purpose of this meta-analysis was to assess the advantage and toxicity profile of chemotherapy plus EGFR-mAbs versus chemotherapy alone for patients with NSCLC.We rigorously searched electronic databases for eligible studies reporting EGFR-mAbs combined with chemotherapy versus chemotherapy alone for patients with advanced NSCLC. The primary outcome was overall survival (OS). Pooled results were calculated using proper statistical methods.Nine phase II/III randomized controlled trials involved a total of 4949 participants were included. In general, compared with chemotherapy alone, the addition of EGFR-mAbs significantly improved OS (hazard ratio [HR] = 0.91, 95% confidence interval [CI]: 0.86-0.97, P = 0.006), progression-free survival (HR = 0.83, 95% CI: 0.87-0.98, P = 0.01), response rate (odd ratio [OR] = 1.28, 95% CI: 1.12-1.47, P = 0.0003), and disease control rate (OR = 1.17, 95% CI: 1.01-1.36, P = 0.04). Subgroup analysis showed that apparent OS benefit present in patients with squamous NSCLC (HR = 0.83, 95% CI: 0.74-0.93, P = 0.001), and those treatment-naive population (HR = 0.88, 95% CI: 0.82-0.95, P = 0.0006). Several manageable adverse events were markedly increased by EGFR-mAbs, such as acne-like rash, infusion reactions, and diarrhea. The risk for some ≥Grade 3 toxicities, such as leukopenia, febrile neutropenia, and thromboembolic events were slightly increased by the addition of EGFR-mAbs. In general, the toxicities of the combination strategy were tolerable and manageable.The addition of EGFR-mAbs to chemotherapy provided superior clinical benefit along with acceptable toxicities to patients with advanced NSCLC, especially those harboring squamous cancer and treatment-naive. Further validation in front-line investigation, proper selection of the potential benefit population by tumor histology, and development of prognostic biomarkers are warranted for future research and clinical application of EGFR-mAbs.
