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
backgroundIn robot-assisted radical prostatectomy (RARP), surgical techniques aimed at preserving urinary continence-such as bladder neck preservation, nerve sparing, and dorsal venous complex (DVC) preservation-are increasingly adopted to improve postoperative quality of life. However, whether an excessive emphasis on functional preservation compromises oncological outcomes remains unclear.
methodsWe retrospectively analyzed 235 consecutive patients who underwent RARP performed by a single experienced surgeon. Patients were stratified according to (1) extent of bladder neck preservation (< 8 mm, 8-16 mm, > 16 mm), (2) nerve-sparing status (bilateral, unilateral, none), and (3) degree of DVC preservation (long, standard, short). Urinary continence at 3 months postoperatively (≤ 1 safety pad/day), positive surgical margin (PSM) rates, and biochemical recurrence (BCR) were evaluated.
resultsBladder neck preservation was associated with improved early continence recovery without increasing PSM or BCR rates. Bilateral nerve sparing resulted in superior continence outcomes; higher PSM rates in the non-nerve-sparing group reflected a more advanced pathological stage. DVC preservation showed the strongest association with continence recovery; however, aggressive DVC preservation was associated with a significantly higher PSM rate, predominantly at the apical and anterior regions. No significant differences in BCR were observed among groups.
conclusionsBladder neck preservation and nerve sparing can improve urinary continence without compromising oncological outcomes when appropriately applied. In contrast, aggressive DVC preservation may increase the risk of positive surgical margins and should be performed cautiously with careful patient selection.
