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
aimsATP-sensitive potassium channels represent promising drug targets for treating specific bladder diseases. The inhibitory effects of ATP-selective potassium channel openers (PCOs) on the carbachol-response curve in porcine detrusor muscle were examined. MATERIALS AND
methodsEach of the three substances used in the study represent one prototype of a different class of PCO: cromakalim belongs to the benzopyran series, pinacidil is a cyanoguanidine derivative, and minoxidil represents a pyrimidine derivative. The porcine detrusor muscle represents one of the best models for human detrusor. Experiments were conducted on muscle strips of porcine detrusor muscle suspended in a tissue bath. Concentration-response curves of carbachol were constructed after pretreatment with cromakalim at 10(-7), 10(-6) and 10(-5) M, and with pinacidil and minoxidil at 10(-6), 10(-5.5) and 10(-5) M, respectively. Each muscle strip was only used to examine one concentration of one substance.
resultsCromakalim had the greatest inhibitory effect, significantly suppressing the carbachol-response curve at 10(-6) and 10(-5) M. Pinacidil showed a significant inhibitory effect at 10(-5.5) and 10(-5) M, which was smaller than that of cromakalim. Minoxidil did not significantly inhibit the contractions at all examined concentrations.
conclusionsThe examined ATP-sensitive PCOs belonging to the benzopyrans and cyanoguanidines significantly suppressed detrusor contractions. The development of derivatives of these prototypes could open new possibilities for the pharmacological treatment of selected bladder diseases.
