Radiofrequency Identification Marker-Guided Right S7 Segmentectomy for a Deeply Located Pulmonary Nodule: A Case Report.
Article in Surgical case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionThe right S7 segment is the smallest pulmonary segment. Securing an adequate surgical margin during S7 segmentectomy can be challenging, particularly when the tumor is located more centrally. Radiofrequency identification (RFID) marking systems provide substantial benefits in detecting small nodules as well as ensuring an adequate resection margin from the marking site. CASE PRESENTATION: A 67-year-old man with a history of renal cell carcinoma was referred to Kyushu University Hospital with a 9-mm solid nodule located deep within the right S7 segment. Given its central and deep location, preoperative RFID marker placement was performed in a hybrid operating room under cone-beam CT guidance. Subsequently, thoracoscopic S7 segmentectomy was performed using a confronting upside-down video-assisted thoracoscopic surgery approach. The RFID probe enabled precise intraoperative localization of the tumor and continuous confirmation of its surgical margin from the intersegmental plane. Pathological examination revealed papillary adenocarcinoma and confirmed complete resection. The patient's postoperative course was uneventful.
conclusionsRFID represents a valuable adjunct for segmentectomy of deeply or centrally located pulmonary nodules.
