Uniportal versus multiportal thoracoscopic lobectomy: Ergonomic evaluation and perioperative outcomes from a randomized and controlled trial.
Trial report in Medicine, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02462356 (A Randomized Controlled Study), which is not on this map. Cited by 12 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.

Abstract
backgroundTo compare perioperative outcomes and surgeon physical and mental stress when performing lobectomy through uniportal and multiportal video-assisted thoracoscopic surgery (VATS) on patients with non-small-cell lung cancer (NSCLC).
methodsPatients aged 41 to 73 years with resectable NSCLC were randomly assigned via a computer-generated randomisation sequence to receive either uniportal VATS (UVATS) or multiportal VATS (MVATS) lobectomy and lymphadenectomy between December 2015 and October 2016. Overall, we randomly assigned 35 patients to the UVATS and 34 to the MVATS group. Patients and the investigators undertaking interventions, assessing short-term outcomes, performing ergonomic evaluations, and analyzing data were not masked to group assignment.
resultsPatient demographics of the 2 groups were comparable. The ergonomic evaluation considered eye blink rate and the NASA Task Load Index (NASA-TLX), better results were observed in UVATS than in MVATS. The operative time, number of lymph nodes harvested, chest tube duration, length of hospital stay, and lung function were not significantly different between the groups. Compared with MVATS lobectomy, UVATS lobectomy was associated with less intraoperative blood loss and less volume of total drainage in the 24 hours. No conversion, no reoperation, and no in-hospital mortality occurred in either group.
conclusionsUVATS lobectomy is a safe and programmable technique with some better perioperative outcomes and ergonomic results than MVATS. Further studies based on large numbers of patients and with long-term follow-up are required to confirm its benefits towards patients.
