Risk factors of conversion in robotic- and video-assisted pulmonary surgery for non-small cell lung cancer.
Article in Updates in surgery, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 3 of them syntheses 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
backgroundThis study aimed to investigate risk factors of conversion to thoracotomy for patients with non-small cell lung cancer (NSCLC) underwent robotic- (RATS) or video-assisted thoracoscopic surgery (VATS).
methodsA retrospective review was conducted to included consecutive participants from January 2016 to December 2018. Three groups [mini-invasive, conversion, and up-front open thoracotomy (OT) groups] and two series of comparison (conversion versus mini-invasive, and conversion versus OT) were generated. Propensity score-matched analysis (1:1) was conducted to verify outcomes of complications and perioperative factors. Multivariate binary logistic regression analysis was used to identify potential risk factors of conversion.
results1177 patients (912 in mini-invasive group, 180 in conversion group, and 85 in OT group) were included. The overall conversion rate was 16.5%. Robotic approach resulted in dramatically lower conversion rate compared to VATS (2.4% vs 25.1%, p < 0.001). After propensity adjustment, no significant difference of complication rates was identified when comparing conversion group with mini-invasive and OT groups. Multivariate regression analyses shown that robotic approach (odd ratio (OR) = 0.037, 95% confidential interval (CI) 0.016-0.087), tumor size < 5 cm (OR = 0.274, 95% CI 0.152-0.493), no chief symptom(OR = 0.311, 95% CI 0.178-0.545), body mass index < 25 kg/m
conclusionsSeven demographic factors might be recognized as independent predictors of conversion. For patients with highly risk of conversion, robotic approach is recommended to perform mini-invasive pulmonary surgery over VATS.
