1 · What the graph read from it

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.

2 · The registry

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

aimTo investigate the prevalence of retinal pathology in patients with a history of exposure to pentosan polysulfate sodium (PPS).

methodsPatients exposed to PPS and seen in the ophthalmology clinic at Northwestern University during 1/1/2002 to 1/1/2019 were identified from electronic health records (EHR) by an electronic data warehouse (EDW) search. Visual acuity (VA), reasons for clinic visit, ocular conditions, and duration of exposure to PPS were noted. Chart review was performed for fundus exam findings and ophthalmologic imaging, specifically fundus photography, fundus autofluorescence, and ocular coherence tomography (OCT) images. When OCT or fundus photography was available, studies were evaluated by two independent graders.

resultsA total of 131 patients who were exposed to PPS and seen at the Northwestern Ophthalmology clinic were identified in the EHR. Forty patients of 131 had imaging. Patients with imaging or fundus examination suspicious for PPS maculopathy were placed into the suspect group. Of the 40 patients that had imaging, 5 (12.5%) had features suspicious for PPS maculopathy. Of the remaining 91, 5 (5.4%) had macular pigmentary changes described on fundus exam. Among the 10 patients in the suspect group, the average duration of PPS use was 4.2 years (range 0.3-11.6 years, interquartile range 5.5 years) and the average cumulative dose was 380g (range 29-1092g, interquartile range 132g).

conclusionA novel drug-induced maculopathy has been associated with PPS use with a distinct clinical constellation that can be accurately identified with multimodal imaging.
