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
introductionLateral local recurrence (LLR) is a recognized pattern of local recurrence in patients with low rectal cancer (LRC) following curative resection, and salvage surgery for LLR is technically challenging. Recent studies have reported the feasibility of robotic lateral lymph node dissection (LLND) in patients with LRC; however, data regarding the safety and usefulness of robotic salvage surgery for LLR after LLND remain limited. Herein, we report a case of robotic salvage tumor resection with combined resection of the internal iliac vessels (IIVs) and ureter for LLR following LLND. CASE PRESENTATION: A 65-year-old man underwent low anterior resection with LLND for LRC without preoperative treatment. The pathological diagnosis was pT3N1bM0, stage IIIB, and adjuvant chemotherapy was administered. LLR was detected 4 years after the initial surgery. Following preoperative long-course chemoradiotherapy (pre-CRT), the patient underwent robotic tumor resection with combined resection of the IIVs and ureter. Ureteroneocystostomy with psoas hitch was subsequently performed. The lumbosacral nerve trunk and sacral plexus were preserved. The operative time was 295 min, and the estimated blood loss was 40 mL. A negative resection margin was obtained. The patient remained recurrence-free at 6 months of follow-up.
conclusionsThis case demonstrates that robotic salvage surgery for LLR following LLND is feasible and can achieve oncologically adequate resection in a minimally invasive modality. The combination of the technical advantages of robotic surgery and tumor regression following pre-CRT may facilitate an optimal balance between oncological radicality and functional preservation.
