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
objectiveTo investigate the learning curve and clinical efficacy of aortic dissection and non-dissection aortic surgeries through upper hemisternotomy.
methodsWe retrospectively analyzed the perioperative data of aortic dissection and non-dissection surgeries through upper hemisternotomy performed by the same surgical team. Based on cardiopulmonary bypass time and aortic cross-clamping time, the learning curves were plotted using cumulative (CUSUM) analysis and the fitting curve, and the learning process was divided into the improvement period and proficiency period. We compared the perioperative parameters in the two stages, and verified whether the critical point was the number of operations required to overcome the learning curve. The safety and short-term efficacy of the aortic surgeries were analyzed after achieving proficiency.
resultsA total of 107 patients were analyzed, including 47 undergoing aortic dissection (ascending aorta replacement + arch replacement + descending aorta stent implantation and/or aortic root treatment) and 60 undergoing non-dissection surgeries (artery root surgery and/or ascending aorta replacement). The optimal fitting equation was
conclusionBoth aortic dissection and non-dissection surgeries through upper hemisternotomy are safe and can significantly improve the short-term postoperative efficacy after achieving proficiency, but the latter approach has a shorter learning curve.
