Assessing the Therapeutic Response to Pirfenidone in Idiopathic Pulmonary Fibrosis: Can We Do Better than with Forced Vital Capacity Alone?
Article in Lung, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02632123 (Validation of the Risk Stratification Score in Idiopathic Pulmonary Fibrosis), which is not on this map. Cited by 6 papers, 1 of them a synthesis that pooled 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.
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.

Abstract
abstarctNew anti-fibrotic agents for idiopathic pulmonary fibrosis (IPF) were approved based on the results of forced vital capacity (FVC) trends, although concerns were raised about the reliability of FVC as the only endpoint parameter. We hypothesized that IPF-specific multi-dimensional scores (Composite Physiologic Index-CPI; gender-age-physiology-GAP; risk stratification score-RISE) would better capture response to therapy. In this pilot study, treated and untreated cohorts of IPF patients, matched for demographic and functional characteristics were prospectively followed for 1 year, at 4-month intervals. Progression-free survival was significantly improved in treated patients (p = 0.0093). While no difference in FVC longitudinal trends was observed, MRC dyspnea score (p = 0.0347), diffusing lung capacity (p = 0.0015), 6-min walk distance (p = 0.0007), CPI (p = 0.0457) and RISE (p = 0.0005) were significantly stabilized in treated patients, compared to steady worsening in untreated subjects. Multi-dimensional scores provide broader spectrum of prognostic information and may facilitate the assessment of efficacy of new drugs for IPF.
