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
Chemically-induced urinary bladder cancer in rodents has long been used as a reliable model to study the biopathology of urinary bladder neoplasia and to develop therapeutic strategies against human tumors. Knowledge of the genetic basis underlying carcinogenesis would greatly enhance usability and usefulness of this model for the purposes of comparative pathology. However, little is known about the cytogenetic characteristics of rodent urinary bladder tumors. Accordingly, pathological and negative control specimens were collected for cytogenetic evaluation, from an ongoing mouse urinary bladder N-butyl-N-(4-hydroxybutyl) nitrosamine-induced carcinogenesis study. Histopathological analysis characterized the pathological sample as a papillary urothelial carcinoma. Conventional cytogenetic analysis revealed the presence of 66.3 % tetraploid cells. Fluorescent in situ hybridization using chromosome paint probes allowed the detection of a reciprocal translocation involving chromosomes 4 and 14 (containing the murine homologues to human p16 and retinoblastoma tumor-suppressor genes) in 42 % of tetraploid cells. The control sample showed no histological or cytogenetic changes. CDKN2A and RB1 loss of heterozygosity is associated with human early and advanced urinary bladder cancer, respectively. Thus, the present data paves the way for further studies concerning the molecular mechanisms of urinary bladder carcinogenesis.
