Predictive effect of XRCC3 Thr241Met polymorphism on platinum-based chemotherapy in lung cancer patients: meta-analysis.
Synthesis in Tumour biology : the journal of the International Society for Oncodevelopmental Biology and Medicine, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Previous published data on the association between X-ray repair cross-complementing group 3 (XRCC3) Thr241Met polymorphism and clinical outcome of platinum-based chemotherapy in patients with lung cancer reported conflicting results. A meta-analysis was performed to provide a systematic review of the published data. We retrieved the relevant studies from PubMed and Embase databases. The primary outcome was overall survival, and the hazard ratio (HR) with 95% confidence interval (95% CI) was estimated. Seven studies with a total of 1,514 patients were included into the meta-analysis. Overall, XRCC3 Thr241Met polymorphism had no influence on the overall survival of lung cancer patients receiving platinum-based chemotherapy (MetMet vs. ThrThr: HR = 0.82, 95% CI 0.52-1.31, P = 0.410; MetThr vs. ThrThr: HR = 0.93, 95% CI 0.79-1.10, P = 0.339; MetMet/MetThr vs. ThrThr: HR = 1.07, 95% CI 0.88-1.31, P = 0.480). There was no obvious risk of publication bias. Therefore, currently available data suggest that there is no predictive effect of XRCC3 Thr241Met polymorphism on platinum-based chemotherapy in lung cancer patients.
