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
Purpose: This study aimed to evaluate whether two commonly overlooked technical choices, preoperative skin marking and electrocautery use, independently affect procedural success and long-term outcomes, using implantable venous port catheter placement as a model procedure within minor surgery. Methods: This retrospective single-center study analyzed 1,122 consecutive port catheter placements, used as a model minor surgical procedure, performed by a single surgeon between June 2022 and September 2025. Preoperative skin marking and electrocautery use were recorded as primary technical variables. The primary outcome was port catheter revision requiring surgical intervention. Learning curve effects were assessed using cumulative sum (CUSUM) analysis. Multivariable logistic regression and Kaplan-Meier analyses were performed to identify independent predictors. Results: Omission of preoperative skin marking was the sole independent predictor of procedural failure in port catheter placement, increasing failure risk 6.07-fold (odds ratio [OR], 6.07; 95% confidence interval [CI], 2.63-14.01; P < 0.001). Port catheter revision occurred in 4.2% of patients. Electrocautery use was a strong independent predictor of revision (OR, 8.89; 95% CI, 1.77-44.70; P = 0.008) and was associated with significantly lower revision-free survival (hazard ratio, 3.52; P = 0.002). CUSUM analysis demonstrated that the reduction in port catheter revisions after electrocautery discontinuation occurred independently of the overall learning curve. Conclusion: Preoperative skin marking improves procedural accuracy, while avoidance of electrocautery markedly reduces revision risk, independent of surgical experience, highlighting the critical impact of routine technical decisions in port catheter placement as a model of minor surgical procedures.
