Application of three-dimensional reconstruction combined with dial positioning in small pulmonary nodules surgery.
Article in Journal of cardiothoracic surgery, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled 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.
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
backgroundWith the popularization of HRCT and VATS, the incidence of early stage lung cancer is increasing recent years. About 63% of small pulmonary nodules can not be accurately identified in VATS. We use 3-D reconstruction combined with dial positioning to analyze its accuracy and impact on patients undergoing VATS in our hospital.
methodAll patients underwent HRCT scanning and 3-D reconstruction preoperatively to determine the scope of surgery. The precise positional relationship between the nodule and the nearest rib must be recorded. Locate the plane of pulmonary nodule on CT, rotate the plane to make the affected side upwards, take the highest point of pleura as 12 o'clock on the dial, record the corresponding point of the nodule meticulously, mark the pulmonary nodule on the skin of the patient. A 18G indwelling needle was used to puncture through the marker into the visceral pleura. Electrocautery mark was made on the bleeding point of the lung surface. Then wedge resection or segmental resection was made. MATERIALS AND
resultFrom September 2019 to December 2020, 74 patients underwent VATS pulmonary nodule resection in our institute, with an average age of (56.4 ± 11.7) years old. A total of 83 nodules were resected in 74 patients, 23 nodules received segmentectomy and 60 nodules received wedge resection with 16 benign nodules and 67 malignant nodules. The distance between the nodules and pleura was (0-25) mm, with an average of (8.0 ± 3.9) mm. The target nodules were found in all patients, the positioning accuracy was 97.6%. All patients were satisfied with the positioning method, and there was no scar left at the skin puncture point after operation.
conclusion3-D reconstruction combined with dial positioning method can reduce patients' anxiety preoperatively, avoid various complications, reduce hospitalization expenses, and has an acceptable accuracy and short learning curve, which can be further promoted and applied in clinic.
