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 explore the mechanism and efficacy of the modified bladder neck intussusception in laparoscopic radical prostatectomy (LSRP) on postoperative early continence.

methodsWe prospectively collected clinical information of prostate cancer patients who underwent LSRP with modified bladder neck intussusception (n = 10) and non-intussusception (n = 10). At postoperative 1 month, the prostate-specific antigen (PSA), pad test, real-time magnetic resonance imaging (rt-MRI), and flow rate were performed. At postoperative 3 months, the PSA, pad test, international prostate symptom score (IPSS), overactive bladder symptom score (OABSS), incontinence questionnaire short form (ICI-Q-SF), and quality of life (Qol) were recorded.

resultsThe intussusception and non-intussusception patients had similar baseline characteristics. At postoperative 3 months, intussusception patients had lower OABSS than non-intussusception patients (P = 0.038). The non-intussusception patients suffered from more severe incontinence (P = 0.026). The continence rate of intussusception patients was significantly higher (90% vs. 20%, P = 0.005). And intussusception patients had significantly lower Qol scores (P = 0.038). According to the morphologic analysis by rt-MRI, there were 7/10 non-intussusception patients and 2/10 intussusception patients having funnel-shaped bladder necks at Valsalva movement. The intussusception patients had larger angle between anterior and posterior wall at bladder neck (P = 0.029) and longer length of functional posterior urethra (P = 0.029). During micturition, the intussusception bladder neck was found to move less dynamically on X-axis and Y-axis, but the difference did not reach significance.

conclusionsThe modified technique of bladder neck intussusception in laparoscopic radical prostatectomy prolongs the length of functional posterior urethra and is effective to improve postoperative early continence.
