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
objectiveTo describe the laterally extended parametrectomy (LEP) surgical technique, emphasizing the main challenges of the procedure.
methodsLEP was designed as a more radical surgical procedure aiming to remove the entire parametrial tissue from the pelvic sidewall. Its initial indications were for lymph node positive Stage Ib (current International Federation of Gynecology and Obstetrics 2018 Stage IIIc) and Stage IIb cervical cancer. Currently, with most guidelines recommending definitive radiochemotherapy for these cases, initial LEP indications have become debatable. LEP is now mainly indicated for removing tumors involving the soft structures of the pelvic sidewall during a pelvic exenteration, aiming to obtain lateral free margins. This expands the lateral borders of the dissection to not only the medial surface of internal iliac vessels, but also to the true limits of the pelvic sidewall.
resultsDuring LEP, the parietal and visceral branches of the hypogastric vessels are divided at the entry and exit level of the pelvis. Consequently, the entire internal iliac system is excised, and no connective or lymphatic tissue remain on the pelvic sidewall. The main technical challenges of LEP are caused by the difficulty in ligating large caliber vessels (internal iliac artery and vein) and the variable anatomic distribution of pelvic sidewall veins.
conclusionLEP is a feasible technique for removing pelvic sidewall recurrences, aiming to obtain surgical free margins.
