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

purposeWe compared the intraoperative and postoperative outcomes of single-port robot-assisted laparoscopic pyeloplasty (S-RALP) using the da Vinci SP® system and conventional multi-port robot-assisted laparoscopic pyeloplasty (M-RALP) in pediatric patients. MATERIALS AND

methodsMulti-port and single-port pyeloplasty have been performed in pediatric patients in our institution since October 2015 and February 2019, respectively. We conducted an entire cohort comparison. Considering the learning curve of M-RALP, we defined the last 15 cases of M-RALP as a subgroup of M-RALP and compared this subgroup with the entire cohort of S-RALP patients.

resultsThirty-one patients who underwent multi-port pyeloplasty and 15 patients who underwent single-port pyeloplasty were enrolled in this study. Age, height, body weight, laterality, surgical indication, and ipsilateral differential renal function were statistically similar in the M-RALP and S-RALP groups. The median operative time (3.0 h vs. 2.4 h; p=0.01) and the median console time (2.2 h vs. 1.5 h; p<0.001) were longer in the M-RALP group than in the S-RALP group. There was no significant difference in operative time or console time between the M-RALP subgroup and the S-RALP group. There were no significant differences in the length of hospitalization, pain score, morphine-equivalent use of analgesics, or postoperative differential renal function in all comparisons.

conclusionsThis study confirmed that pyeloplasty using the da Vinci® SP system can be started by robotic surgeons who can overcome the learning curve. Robot-assisted laparoscopic single-port pyeloplasty is feasible in noninfant pediatric patients.
