Imaging of Resected Nonfunctioning Pituitary Adenomas: The Cost of Surveillance.
Article in Journal of neurological surgery. Part B, Skull base, 2015. 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
Objectives To determine the cost of annual magnetic resonance imaging (MRI) surveillance after resection of nonfunctioning pituitary adenomas (NFPAs) and its effectiveness in reducing visual compromise due to tumor recurrence. Design Retrospective case series. Setting Vanderbilt University Medical Center (2003-2011). Participants A total of 120 patients underwent primary transsphenoidal resection and surveillance of NFPAs between 2003 and 2011. Main Outcome Measures Time from initial surgery to most recent imaging or progression. Surveillance MRI costs according to Centers for Medicare and Medicaid database and visual field deficits. Results Patients received 382 surveillance scans at a total cost of $218,477.30. The median follow-up was 47 months (interquartile range [IQR]: 26-76), and the median interval between scans was 357 days (IQR: 225-434). Overall, 50 scans (13%) revealed tumor growth. The cost per scan revealing growth was $4,369.55. The cost to identify 19 patients (16%) with clinically significant growth was $11,498.80 per patient. A total of 5 of 19 patients (26%) experienced new visual deficits prior to intervention. Patients with visual decline tended to have longer scan intervals than those with preserved vision (mean: 239 versus 794 days; p = 0.0584). No patient with annual surveillance imaging experienced visual decline. Conclusions Annual MRI scans are a sensitive and cost-conscious method to identify NFPA recurrence prior to visual decline.
