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
The association between DNA repair gene polymorphisms and bladder cancer risk has been widely studied. However, only few studies have examined the correlation between bladder cancer and instillation agent sensitivity. The aim of this study was to examine the association between polymorphisms of DNA repair genes, namely X-ray repair cross-complementing group I (XRCC1) rs2854509 and rs3213255, and bladder cancer recurrence risk. We recruited 244 patients (130 treated with epirubicin and 114 treated with mitomycin C). Genomic DNA was used to examine the XRCC1 rs2854509 and rs3213255 genotypes by Taqman PCR analysis. Combination analysis of XRCC1 rs2854509 and rs3213255 and examination of XRCC1 diplotypes were performed to reveal possible correlations. The rs2854509 CC and rs3213255 TT genotypes conferred shorter survival times than the rs2854509 AC/AA and rs3213255 CC/CT genotypes in patients treated with epirubicin, but not in those treated with mitomycin C (MMC) in adjusted models [hazard ratio (HR) = 0.23, 95 % confidence interval (CI) = 0.10-0.53 for rs2854509 AC + AA compared with CC; HR = 0.17, 95 % CI = 0.06-0.46 for rs3213255 CC + CT compared with TT]. Combination analysis showed significantly increased recurrence-free survival (RFS) among patients simultaneously carrying the rs2854509 AC/AA and rs3213255 CC/CT genotypes with an HR of 0.15 (95 % CI = 0.05-0.45) compared to those carrying other genotypes. Diplotype analysis demonstrated that the A-C/C-T diplotype is associated with a lower risk of recurrence compared with the common wild C-T/C-T diplotype (HR = 0.17, 95 % CI = 0.06-0.51). Our results suggest that the rs2854509 CC and rs3213255 TT genotypes confer higher sensitivity to epirubicin instillation. Moreover, the A-C/C-T diplotype presents significantly lower recurrence risk than other diplotypes.
