Open Conversion at Robotic Adrenalectomy: Rates and Predictors.
Article in Journal of surgical oncology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundRates and predictors of open conversion at robotic adrenalectomy (rRA) are unknown.
methodsWe identified patients treated with rRA (National Inpatient Sample 2009-2019). First, temporal trends in open conversion were assessed using Estimated Annual Percentage Changes (EAPC). Second, multivariable logistic regression models were used to identify predictors of open conversion during rRA.
resultsOf 2,292 rRA patients, 286 (12.0%) underwent open conversion. The rates of open conversion decreased over time from 39.2% to 10.2% over the study span (EAPC -15.9%; p = 0.0003). Open conversion patients during rRA were more frequently male (59.0 vs. 53.0%; p = 0.04) and had more comorbidities (Charlson Comorbidity Index [CCI] ≥ 4: 28.0 vs. 17.0%; p < 0.001). In multivariable logistic regression models predicting open conversion, CCI ≥ 4 versus 0-3 (OR: 2.0; p < 0.001) and low versus medium-high surgical volume hospital (OR: 2.0; p < 0.001) were independent predictors. A dose-response effect was observed when CCI and hospital volume were combined. Specifically, the rates of open conversion were respectively 13.9 versus 25.9% in patient with CCI 0-3 versus CCI ≥ 4 at low surgical volume hospitals (p < 0.001). Conversely, the rates of open conversion were respectively 7.7 versus 13.4% in patient with CCI 0-3 versus CCI ≥ 4 at medium-high surgical volume hospitals (p < 0.001).
conclusionThe rate of open conversion at rRA significantly decreased over time from 39.2% to 10.2%. Individuals at particularly elevated risk consisted of patients with CCI ≥ 4 in whom rRA is contemplated at low-volume hospitals (25.9%). Relegation of such individuals to medium-high surgical volume hospitals may reduce the conversion rate by half (13.4%).
