Factors Affecting Best-Tolerated Dose of Pirfenidone in Patients with Fibrosing Interstitial Lung Disease.
Article in Journal of clinical medicine, 2023. 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
The aim of the study was to examine the best-tolerated dose of pirfenidone, the adverse effects profile, and potential factors other than drug dose influencing the tolerability of pirfenidone in patients with fibrosing interstitial lung diseases (ILDs). We performed an observational retrospective study of 113 patients with IPF and other fibrosing ILDs treated with pirfenidone. Baseline liver function tests (LFTs) and dose escalation of pirfenidone were recorded for all patients. The best-tolerated dose was continued if the patient did not tolerate full dose (2400 mg) despite repeated dose escalation attempts. Potential risk factors such as age, height, weight, body mass index (BMI), body surface area (BSA), gender, smoking, and presence of comorbidities were analyzed between 3 groups of best-tolerated pirfenidone doses: 2400 mg/day vs. <2400 mg/day, 2400 mg/day vs. 1800 mg/day, and 2400 mg/day vs. 1200 mg/day. A total of 24 patients tolerated 2400 mg/day, and 89 patients tolerated <2400 mg/day (43 tolerated 1800 mg/day, 45 tolerated 1200 mg/day and 1 tolerated 600 mg/day). Patients who tolerated 2400 mg/day were taller and had a larger BSA as compared to those tolerating <2400 mg/day. Overall, males tolerated the drug better. Presence of comorbidities or smoking did not affect the tolerance of pirfenidone, except for the presence of cerebrovascular diseases. Various adverse effects did not have any significantly different frequencies between the compared groups. Moreover, 71.7% of patients experienced at least one side effect. 1200 mg/day was the best-tolerated dose in the majority of the patients. Male patients with a larger BSA and greater height showed better tolerability of pirfenidone overall.
