The Dose-Response Relationship of bacillus Calmette-Guérin and Urothelial Carcinoma Cell Biology.
Article in The Journal of urology, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
purposeAttenuated mycobacterium bacillus Calmette-Guérin is widely used as intravesical immunotherapy of nonmuscle invasive urothelial carcinoma. Currently there are limited data on the relationship between bacillus Calmette-Guérin dose intensity and tumor response. We evaluated the dose-response relationship of bacillus Calmette-Guérin to nonmuscle invasive bladder cancer in vitro using urothelial carcinoma cell lines and in vivo using an orthotopic mouse model. MATERIALS AND
methodsTwo human urothelial carcinoma cell lines were used to study the effect of bacillus Calmette-Guérin dose on the tumor cell response. Internalization, activation of signaling pathways, gene transactivation, cell viability, lactate dehydrogenase and HMGB1 release were study end points. An orthotopic tumor model was used to compare the effect of different doses on the antitumor efficacy of bacillus Calmette-Guérin.
resultsBacillus Calmette-Guérin internalization by urothelial carcinoma cells increased as a function of time and dose with a plateau at higher doses and/or long exposure times. Intracellular signaling demonstrated a similar direct, dose dependent increase. Cytokine expression by urothelial carcinoma cells as a function of dose was variable. Some genes increased progressively but others showed a decrease at the highest dose. While nonviable cell number increased in proportion to dose, the number of cells undergoing necrotic cell death decreased at higher doses. A higher dose of bacillus Calmette-Guérin (1:200) showed a better antitumor effect than a standard dose (1:50) (p <0.01).
conclusionsBacillus Calmette-Guérin dose has a direct impact on urothelial carcinoma cell biology. Increased dose intensity, particularly in nonresponders, may represent a strategy to increase bacillus Calmette-Guérin treatment efficacy.
