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.

Abstract
objectivesHybrid operating rooms (HORs) incorporating robotic C-arm systems facilitate concurrent localization and resection of small pulmonary nodules, albeit with significant cost barriers. Contemporary mobile 3 D C-arm systems may provide superior soft tissue visualization with enhanced economic viability and accessibility. This prospective single-arm clinical pilot trial was designed to assess the technical feasibility, clinical efficacy, and procedural safety of employing mobile 3 D C-arm technology for single-stage localization and excision of small pulmonary nodules.
methodsPatients presenting with small and/or deep-seated lung tumors necessitating preoperative localization were eligible for inclusion. Two distinct mobile 3 D C-arm systems (Cios Spin and Ziehm Vision RFD 3 D) were employed. The primary end-points included the rate of successful tumour localization and the time required to complete the localization procedure. Secondary end-points encompassed perioperative complications and radiation exposure.
resultsThe study cohort included 41 patients with lung tumors measuring a median diameter of 7.30 mm (interquartile range [IQR]: 5.00-9.20 mm) and a median depth of 10.00 mm (IQR: 2.00-18.00 mm). Successful localization was achieved in 40 patients, yielding a success rate of 97.6%. In one case, inadequate lesion visualization using the mobile 3 D C-arm necessitated localization in a hybrid operating room. The mean localization time was 27.17 ± 10.38 min, and the median radiation exposure was 531.04 μGy m2 (IQR: [297.12-870.98] μGy m2). All patients were successfully discharged, with a median postoperative hospital stay of 3 days (IQR: 3-3 days).
conclusionsOur results support the technical feasibility, clinical efficacy, and procedural safety of mobile 3 D C-arm systems for single-stage localization and resection of small pulmonary nodules. CLINICAL TRIAL REGISTRATION NUMBER: ClinicalTrials.gov identifier: NCT04974632.
