Cost-effectiveness of hydroxychloroquine retinopathy screening: the current guideline versus no screening and reduced regimens.

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
objectiveHydroxychloroquine (HCQ) effectively treats autoimmune diseases but prolonged use may lead to retinopathy and subsequent vision loss. Guidelines suggest annual follow-up after 5 years for low-risk and 1 year for high-risk patients. This study evaluates the cost-effectiveness of current screening guidelines and a reduced regimen in the Netherlands from a societal perspective.
methodsA Markov model assessed costs and quality-adjusted life-years (QALYs) for current and reduced screening regimens. The model included 359 HCQ-treated patients from Radboud University Medical Center. Cost-effectiveness was examined in the general population and patients using < 5.0 mg/kg, 5.0-6.0 mg/kg, or > 6.0 mg/kg HCQ per day for several reduced regimens.
resultsCompared to no screening, the current screening guideline saves costs (i.e., €210 per patient), while gaining QALYs (i.e., 0.79 QALY per patient) over a lifetime in the Netherlands. However, in patients receiving < 5.0 mg/kg HCQ per day, a biennial screening regimen after 10 years using SD-OCT was more cost-effective. For those with 5.0-6.0 mg/kg and > 6.0 mg/kg per day, initiating annual screening with an SD-OCT after 5 years was more cost-effective than the current guideline.
conclusionsScreening for HCQ retinopathy is cost-effective, but delayed initiation and a reduced frequency, using solely an SD-OCT, are more cost-effective. We recommend screening with an SD-OCT and a biennial regimen after 10 years for low-risk patients, an annual regimen after 5 years for intermediate- and high-risk patients.
