Prospective evaluation of candidate urine and cell markers in patients with interstitial cystitis enrolled in a randomized clinical trial of Bacillus Calmette Guerin (BCG).
Trial report in World journal of urology, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 2 of them syntheses that pooled it.
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
We measured candidate urine biomarkers and bladder cell DNA cytometry in interstitial cystitis (IC) patients randomized to receive intravesical Bacillus Calmette Guerin (BCG) or placebo in a multicenter trial. Participants received 6 weekly instillations and were followed for 34 weeks. Urine was collected at baseline, prior to fourth treatment, and at study end. Antiproliferative factor (APF) activity was determined by 3H-thymidine incorporation assay; heparin-binding epidermal growth factor-like growth factor (HB-EGF) and epidermal growth factor-like growth factor (EGF) levels were determined by ELISA. Cellular DNA content was measured by image analysis to determine the mean hyperdiploid fraction (HDF) of the urine cell pellet. Associations between marker levels, and treatment or symptoms, were examined. Baseline APF positivity rate and mean levels of the other biomarkers were similar to previous smaller studies. During the week 34 follow-up, mean HDF decreased (P = 0.0003) and HB-EGF increased (P < 0.0001); both correlated weakly with decreased urgency. There was no difference in any biomarker between symptom responders and non-responders, but the percentage of responders was low and not significantly different for BCG versus placebo. APF positivity, decreased HB-EGF, increased EGF, and increased HDF were confirmed at baseline in IC patients. Changes in HDF and HB-EGF levels correlated weakly with changes in urgency, but the low BCG response rate prevented identification of additional associations between biomarker changes and treatment or symptoms.
