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

purposeTo describe a novel single-position intraperitoneal laparoscopic surgery (SP-ILS) technique for radical nephroureterectomy (RNU) and bladder cuff excision (BCE) in the supine position.

methodsBetween January 2019 and June 2023, 40 patients with UTUC underwent laparoscopic RNU and BCE using the SP-ILS technique. Clinical, perioperative, and pathological data were retrospectively analyzed.

resultsAll procedures were performed laparoscopically without patient repositioning. No intraoperative or postoperative complications occurred. The mean operative time was 101.0 ± 24.5 minutes, and mean estimated blood loss was 53 ± 27.0 mL. The median postoperative hospital stay was 4.2 ± 1.1 days. Postoperative pathology revealed Ta in 14 patients, T1 in 21 patients, and T2 in 5 patients. During a mean follow-up of 12.9 months (range, 2-24), one patient developed bladder recurrence.

conclusionsThe SP-ILS technique offers direct visualization, reproducible bladder cuff excision, and efficient single-position workflow during both LRNU and BCE.
