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

backgroundReconstructing the urethra presents in hypospadias surgery is difficult. Occasionally, the urethral plate (UP) may be quite narrow, necessitating augmentation or replacement to achieve additional tubularization.

objectiveThe objective of this research was to assess the application of modified dorsal inlay graft (mDIG) and tubularized incised plate (TIP) urethroplasties in patients with hypospadias and narrow UPs and to determine which method yields superior functional and surgical outcomes. MATERIALS AND

methodsThe medical records of 114 patients with distal/midshaft hypospadias and narrow UPs who were treated at our hospital from December 2020 to June 2024 were analyzed in this retrospective cohort study. These individuals were categorized into two distinct groups: the TIP and the mDIG groups. Standard preoperative characteristics, surgical technique, postoperative complication rate, maximum urinary flow rate (Q

resultsNo significant differences in patient age, meatus location, UP width, coronal diameter, or urethral length were observed between the two groups. Sixty-five patients (57.0%) underwent TIP urethroplasty, and 49 patients (43.0%) underwent mDIG urethroplasty. A statistically significant difference in operative time was observed, with operative times of 108 (101-118.5) and 85 (78-92.5) min (p < 0.001) in the mDIG and TIP groups, respectively. The mDIG group demonstrated a better HOSE score than the TIP group, with 5 (10.2%) versus 18 (27.7%) patients scoring less than 16 points and 44 (89.8%) patients versus 47 (72.3%) scoring 16 points, respectively. Three months after surgery, the Q DISCUSSION AND

conclusionmDIG urethroplasty has a high success rate, ensuring both optimal aesthetic and functional outcomes in the short term, which, justifies the additional operative time.
