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
Intravesical Bacillus Calmette-Guerin (BCG) is the best treatment modality for progression of non-muscle invasive bladder cancer. We aimed to monitor changes at the proteome level to identify putative protein biomarkers associated with the response of urothelial precancerous lesions to intravesical BCG treatment. The rats were divided into three groups (n = 10/group): control, non-treated, and BCG-treated groups. The non-treated and BCG-treated groups received N-methyl-N-nitrosourea intravesically. BCG Tice-strain was instilled into bladder in BCG-treated group. At the endpoint of experiment, all surviving rat bladders were collected and equally divided into two portions vertically from dome to neck. Half of each bladder was assessed immunohistopathologically and the other half was used for 2D-based comparative proteomic analysis. Differentially expressed proteins were validated by Western blot analysis. Precancerous lesions of bladder cancer were more common in non-treated group (77.8%) than in BCG-treated group (50%) and the control group (0%). Greater than twofold changes occurred in the expression of a number of proteins. Among them, Rab-GDIβ, aldehyde dehydrogenase 2 (ALDH2) and 14-3-3 zeta/delta were important since they were previously reported to be associated with cancer and their expression levels were found to be lower in BCG-treated group in comparison to the non-treated group. ALDH2 and 14-3-3 zeta/delta were also found to be highly expressed in the non-treated group compared to the control group. The down-regulation of these proteins and Rab-GDIβ was achieved with BCG; this result indicates that they may be used as putative biomarkers for monitoring changes in bladder carcinogenesis in response to BCG immunotherapy.
