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

backgroundLateral pelvic lymph node dissection (LPND) is a key component in the surgical treatment of advanced pelvic malignancies. Minimally invasive techniques have evolved over the past decade, with laparoscopic surgery as the traditional standard and robotic-assisted surgery emerging as a promising alternative. This study aimed to systematically compare robotic (R-LPND) and laparoscopic (L-LPND) approaches in terms of perioperative outcomes in patients undergoing LPND for advanced pelvic cancers.

methodsA systematic review and meta-analysis were conducted following PRISMA 2020 guidelines. The search was performed until April 1, 2024. The primary outcome was postoperative morbidity. Secondary outcomes included operative time, LPND-specific operative time, hospital stay duration, number of lymph nodes harvested, and rate of major complications.

resultsEleven studies with 667 robotic and 568 laparoscopic cases were included. Robotic LPND was associated with significantly lower postoperative morbidity (OR 0.52; p = 0.02) and shorter hospital stays (MD - 2.30 days; p = 0.0003). However, robotic procedures had significantly longer operative times (MD 40.58 min; p = 0.003). No significant differences were observed in the number of lymph nodes harvested, LPND time, or rates of major complications. Heterogeneity was moderate to high for most outcomes, and the overall certainty of evidence ranged from low to moderate.

conclusionRobotic LPND may offer clinical benefits in terms of reduced morbidity and shorter hospitalization compared to laparoscopic surgery, although it is associated with longer operative time. These findings are based on evidence of low to moderate certainty and should be interpreted with caution due to the predominance of retrospective studies and notable inter-study heterogeneity.
