Efficacy and safety of gemcitabine-based chemotherapies in biliary tract cancer: a meta-analysis.

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
aimTo investigate the efficacy and safety of gemcitabine (Gem)-based combination chemotherapies for the treatment of advanced biliary tract cancer.
methodsClinical trials were identified by searching scientific literature databases (PubMed, EMBASE and the Cochrane Library) for studies published between 1975 and 2013. Two reviewers independently evaluated the relevant studies and manually searched references from these reports to locate additional eligible studies. The disease response and control rates, progression-free and overall survivals, and the grade 3-4 toxicities were evaluated by a meta-analysis. Odds-ratios (ORs) of the disease response and control rates and grade 3-4 toxicities, and the mean difference (MD) of both progression-free and overall survivals were calculated and used for statistical analysis.
resultsSeven randomized trials with a total of 858 patients were selected and included in the final analysis. The studies were divided into subgroups based on the chemotherapy regimens, including Gem-based and non-Gem-based chemotherapies. The overall analyses revealed that the patients treated with Gem-based combination chemotherapy had significantly higher disease response rates [OR = 1.69, 95% confidence interval (CI): 1.17-2.43; P = 0.01], a longer progression-free survival (MD = 1.95, 95%CI: 0.90-3.00; P = 0.00) and a longer overall survival (MD = 1.85, 95%CI: 0.26-3.44; P = 0.02). A higher incidence of grade 3-4 hematological toxicities, including leukopenia (OR = 2.98, 95%CI: 1.44-6.20; P = 0.00), anemia (OR = 2.96, 95%CI: 1.79-4.92; P = 0.00) and neutropenia (OR = 2.80, 95%CI: 1.39-5.64; P = 0.00) was found in the Gem-based combination chemotherapy group compared with the Gem monotherapy and non-Gem-based chemotherapy groups.
conclusionGem-based combination chemotherapy is a potential first-line treatment for advanced biliary tract cancer as a result of improved survival, though with additional toxicity.
