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
introductionSitus inversus totalis (SIT) is a rare congenital condition characterized by the complete mirror-image transposition of the thoracic and abdominal organs. Although arterial anomalies in SIT have been reported, venous anomalies, particularly those involving the portal venous system, are extremely rare and may increase the technical difficulty of minimally invasive surgery. We report a case of laparoscopic distal gastrectomy in a patient with SIT accompanied by a duplicated portal vein (DPV). CASE PRESENTATION: A 75-year-old woman with SIT presented with epigastric discomfort and was diagnosed with gastric cancer and multiple gallstones. Preoperative 3D-CT angiography revealed several vascular anomalies, including a DPV. Laparoscopic distal gastrectomy with D1+ lymphadenectomy and concomitant cholecystectomy was successfully performed using 3 surgical strategies. Preoperative 3D-CT evaluation enabled accurate identification of the vascular anatomy, and intraoperative multimodal visualization using 3 monitors facilitated safe orientation in the mirror-image operative field. Continuous communication between the surgeon and assistant further prevented anatomical misinterpretation. The operative time was 307 min, and blood loss was 50 mL. The postoperative course was uneventful, and the patient was discharged on POD 12. Histopathological examination revealed pT1b, pN0, cM0, and Stage IA gastric adenocarcinoma.
conclusionsCareful attention should be paid not only to mirror-image anatomy but also to vascular anomalies, particularly those of the venous system, in patients with SIT. Detailed preoperative and intraoperative assessments using multimodal visualization in conventional laparoscopic surgery may provide essential anatomical orientation, facilitating safe navigation, dissection, and precise intracorporeal reconstruction.
