Real-World Practice Patterns for Prevention and Management of Potential Adverse Events with Pirfenidone in Patients with Idiopathic Pulmonary Fibrosis.

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
introductionPirfenidone is an oral antifibrotic agent approved for idiopathic pulmonary fibrosis (IPF). Real-world data on adverse event (AE) management for pirfenidone are limited. Strategies for managing potential antifibrotic therapy AEs were examined in a sample of US pulmonologists.
methodsAn online, self-administered survey was fielded to pulmonologists between April 10 and May 17, 2017. Pulmonologists were included if they spent > 20% of their time in direct patient care and had ≥ 5 patients with IPF on antifibrotic therapy. Participants answered questions regarding initiation of pirfenidone, dose titration, and management of potential AEs.
resultsA total of 169 pulmonologists participated. Gastrointestinal (GI) intolerance was the most important factor in implementing alternative titration schedules for pirfenidone. Approximately three-quarters of pulmonologists recommended the standard titration scheme for starting treatment; however, a range of titration schedules up to 8 weeks were described, with a 4-week schedule being most common. Pulmonologists reported that most patients treated with alternative titration schedules could achieve the full dose of pirfenidone. Pulmonologists who were most effective at mitigating pirfenidone-related GI AEs by advising dosing at mealtimes more frequently recommended taking pirfenidone during a substantial meal than pulmonologists who were less effective. For photosensitivity AEs, pulmonologists recommended sunscreen use, sun avoidance, wearing a hat, and ultraviolet protection factor clothing.
conclusionsPulmonologists reported that alternative titration schedules for initiating pirfenidone were common and can aid in maintaining the full dose. Proposed strategies to ameliorate pirfenidone-related GI and photosensitivity AEs included taking pirfenidone during a substantial meal and minimizing sun exposure, respectively.
