1 · What the graph read from 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.

2 · The registry

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

purposeTo investigate the effectiveness of acotiamide on lower urinary tract dysfunction by using a rat model of neurogenic underactive bladder induced through pelvic nerve crush (PNC) injury.

methodsBilateral PNC injuries were performed on 8-week-old female Sprague-Dawley rats (PNC group); the sham surgery group was used as control (control group). Two weeks after surgery, awake cystometrography (CMG) was performed, and acotiamide (10 or 100 mg/kg) was subcutaneously administered to the control and PNC groups. Subsequently, CMG parameter values obtained before and after treatment were compared.

resultsIn baseline CMG, compared to control group, PNC group revealed statistically significant elevations in the intercontraction intervals (ICIs), number of nonvoiding contractions, baseline pressure, threshold pressure, bladder capacity, voided volumes, and postvoid residual. However, contraction amplitudes and voiding efficiency were significantly decreased. In the control group, compared with the baseline values, 10-mg/kg acotiamide resulted in statistically significant elevations in contraction amplitudes. Treatment with 100-mg/kg acotiamide led to statistically significant elevations in contraction amplitudes and decreases in ICI and bladder volume. In the PNC group, there were no statistically significant changes noted in CMG parameters after treatment with 10-mg/kg acotiamide (n=6). Compared with the baseline values, the administration of 100-mg/kg acotiamide significantly decreased ICI (1,025±186 seconds vs. 578±161 seconds; P=0.012), bladder capacity (1,841±323 µL vs. 871±174 µL, respectively; P=0.0059) and postvoid residual (223±46 µL vs. 44±22 µL, respectively; P=0.023), and increased contraction amplitudes (22.09±1.76 cm H2O vs. 43.84±6.87 cm H2O, respectively; P=0.012) and voiding efficiency (0.87±0.02 vs. 0.94±0.03, respectively; P=0.029).

conclusionAcotiamide showed effectiveness in the treatment of underactive bladder, possibly through activation of bladder afferent and detrusor activities.
