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
backgroundSpontaneous ventilation video-assisted thoracoscopic surgery (SV-VATS) has been propagated for nearly two decades without a prospective in-depth analysis of anaesthetic management and anaesthetic processing times. This would be important as anaesthetic management of SV-VATS imposes fundamental changes to standards in thoracic anaesthesia and may increase anaesthetic risks. Therefore, this study aimed to provide such in-depth analysis and compare the results to data from matched intubated VATS (I-VATS) patients. 3D-reconstruction of bronchial airways helped to estimate the risk reduction by avoiding double-lumen tube (DLT) intubation according to common selection methods in SV-VATS patients.
methodsSV-VATS patients receiving anatomical (N = 22) and non-anatomical (N = 16) lung cancer resections were prospectively enrolled. A retrospective I-VATS control cohort (N = 76) allowed for a 2:1 propensity score matching. DLT sizes necessary for SV-VATS patients according to common selection methods were evaluated by 3D-reconstruction of the left main bronchus and the ≥ 1 mm criterion.
resultsSV-VATS patients required substantially less propofol dosage (P < 0.001) with an increase in variability of drug dosing (P < 0.001) and higher BIS values (P < 0.001) as compared to I-VATS patients. SV-VATS lead to higher variability in respiratory parameters (P < 0.001) with less driving pressure (P < 0.001) and similar mean tidal volumes, oxygenation, and hemodynamic parameters compared to I-VATS. Spontaneous ventilation was achieved by allowing for permissive hypercapnia and respiratory acidosis. Anaesthetic processing time was reduced by 7 min (P < 0.001). 5-10% of female and 5% of male patients would have received a DLT larger than their bronchial airway.
conclusionsOur study provides the first prospective quantitative in-depth analysis of a standardised anaesthetic management regime for SV-VATS, including anaesthetic processing times. Respiratory parameters during SV-VATS are compatible with reduced mechanical power as compared to patients undergoing I-VATS. The anaesthetic management regime reduced the risk of airway damage imposed by choosing too-large DLTs in up to 10% of patients without compromising oxygenation and hemodynamic stability. Changes in anaesthetic processing time by 7 min would not allow for a higher caseload of SV-VATS for lung cancer surgery. CLINICAL TRIAL NUMBER: Not applicable.
