Clinical and economic burden of acute exacerbations of idiopathic pulmonary fibrosis: a prospective observational study in Spain (OASIS study).
Observational study in BMC pulmonary medicine, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundIdiopathic pulmonary fibrosis (IPF) is a fatal progressive lung disease entailing significant impairment in health-related quality of life (HRQoL) and high socioeconomic burden. The course of IPF includes episodes of acute exacerbations (AE-IPF) leading to poor outcomes. This study aimed to compare management, costs and HRQoL of patients with AE-IPF to patients without AE-IPF during one year in Spain. MATERIALS AND
methodsIn a 12-month, prospective, observational, multicenter study of IPF patients, healthcare resource use was recorded and costs related to AE-IPF were estimated and compared between patients with and without AE-IPF. HRQoL was measured with the St. George's Respiratory Questionnaire (SGRQ), EuroQoL 5 dimensions 5 levels questionnaire (EQ-5D-5L), EQ-5D visual analogue scale (EQ-VAS) and the Barthel Index.
results204 IPF patients were included: 22 (10.8%) experienced ≥ 1 acute exacerbation, and 182 (89.2%) did not. Patients with exacerbations required more primary care visits, nursing home visits, emergency visits, hospital admissions, pharmacological treatments and transport use (p < 0.05 for all comparisons). Likewise, patients with exacerbations showed higher annual direct health AE-IPF-related costs. In particular, specialized visits, emergency visits, days of hospitalization, tests, palliative care, transport in ambulance and economic aid (p < 0.05 for all comparisons). Exploratory results showed that patients with AE-IPF reported a non-significant but substantial decline of HRQoL compared with patients without AE-IPF, although causality can be inferred.
conclusionWe observed significantly higher resource use and cost consumption and lower HRQoL among patients suffering exacerbations during the study. Thus, preventing or avoiding AE-IPF is key in IPF management.
