Using A Surgical Risk Predictor to Estimate Percutaneous Cryoablation Adverse Event Risk: A Single Center Comparative Analysis.
Article in Journal of the American College of Radiology : JACR, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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 evaluate the relevance of established surgical risk calculators for predicting complications in patients undergoing percutaneous lung cryoablation (PLC).
methodsThe institution's database was queried for PLC procedures from March 2015 to May 2024, excluding those patients with concomitant local therapies or five or more lesions treated in a single setting. Demographics, frailty metrics as defined by the surgical literature, and procedural variables were collected. To evaluate the suitability of surgical risk estimate calculators, the requisite demographic data were input into the American College of Surgery surgical risk calculator; estimates for length of stay (LOS), serious complications, 30-day readmission, and mortality were calculated to determine the comparative risk profile were the patients to have undergone surgical wedge resection instead of PLC. Additionally, to evaluate the suitability of imaging predictors of complications, the volume of emphysematous lung was calculated using a machine learning algorithm and incorporated into a generalized estimating equation logistic regression analysis of other demographic and technical variables.
resultsThe study included 217 patients who underwent 314 procedures. Chest tubes were placed in 49% of procedures. The median LOS was 1 day (interquartile range: 1-1, range: 0-13). The median percentage of emphysema within the lungs was 5.9% (interquartile range: 2.4%-12.1%, range: 0.01%-50.3%). The median predicted surgical rates for serious complications (13.5%), 30-day readmission (12%), and 30-day mortality (5.9%) were all greater than actual rates after PLC (1.6%, 4.8%, and 0.3%, respectively). The estimated surgical LOS differed significantly from the actual PLC LOS (5 days versus 1 day, P < .001). In univariable analysis, the number of probes the number of tumors ablated (odds ratio 1.90, 95% confidence interval 1.18-3.05, P = .008) and the number of probes used (odds ratio 1.44, 95% confidence interval 1.06-1.96, P = .021) were significantly associated with increased LOS, but demographic and emphysema details were not.
conclusionComplications after PLC are significantly less frequent than the estimated complication risks for wedge resection in the same patient population. Risk estimate calculators tailored to PLC would help screen for high complication risks related to this procedure.
