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
introductionAntimuscarinic drugs have frequently been used for the treatment for patients with an overactive bladder (OAB) and there have been many studies on the distribution of muscarinic receptor subtypes in the bladder. However, the distribution of muscarinic receptor subtypes in OAB patients has not been well investigated. In this study we investigated the distribution of muscarinic receptor subtypes with mRNA and protein expressions in patients with and without OAB, and investigated both the dome and trigone area.
methodsSamples of bladder smooth muscle were obtained from 10 individuals, five patients with OAB and a non-OAB group consisting of five patients who received radical cystectomy.
resultsThe M2 receptor was predominant, but there was no significant difference in the level of M2 expression between the groups in the dome area. M5 expression in the dome area was significantly higher in the OAB group than in the non-OAB group. In the trigone area, the level of M2 mRNA expression was the highest in the non-OAB group, and was significantly lower in the OAB group. The levels of M1 and M5 mRNA expression were also observed in samples obtained from the trigone area.
conclusionThe multiformity of the muscarinic receptor subtypes in human bladder smooth muscle was confirmed, and our results suggest that the efficacy of a given pharmacologic therapy differs from patient to patient.
