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

introductionWhen a bulky intra-abdominal tumor cannot be clearly distinguished from a malignancy, careful surgical planning is required to preserve adjacent organs. CASE PRESENTATION: A 31-year-old female presented to our hospital with lower abdominal pain. Contrast-enhanced CT revealed a 67-mm mass in the cecum. Colonoscopy revealed a raised lesion; however, biopsy results were inconclusive. Laparoscopic ileocecal resection with D2 lymphadenectomy was performed because of a suspected malignancy. Given the proximity of the tumor to the right ureter on preoperative imaging, a fluorescent ureteral catheter (FUC) was inserted preoperatively. Intraoperatively, near-infrared light enabled a clear ureteral visualization, thereby facilitating safe dissection and successful preservation. Her postoperative course was uneventful. Pathological examination revealed a spindle cell lesion with suppurative inflammation, and immunostaining indicated myofibroblastic differentiation consistent with an appendiceal inflammatory pseudotumor.

conclusionsThis case highlights the utility of FUC-guided navigation for ureteral preservation during minimally invasive surgery for bulky intra-abdominal masses.
