Associations with short-term and long-term use of inhaled corticosteroid in adults with asthma. A retrospective analysis.
Article in Revista da Associacao Medica Brasileira (1992), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveThe objective of this study was to compare anthropometric data and pulmonary and extrapulmonary physical functional outcomes of short- and long-term use of inhaled corticosteroids in adults with asthma.
methodsThis cross-sectional study with retrospective analysis included clinically stable adults with asthma. Anthropometric data, exacerbation history, pulmonary function, disease control, dyspnea in daily life, quality of life, anxiety, depression, functional exercise capacity, performance in daily activities, body composition, physical activity level, respiratory muscle strength, lower limb strength, and handgrip strength were assessed and compared. Participants were separated into two groups based on the current duration of inhaled corticosteroids use below (short-term) or above (long-term) 3 years (≤3 years [n=37] and >3 years [n=30]) for comparative analysis.
resultsA total of 67 participants were analyzed (69% female, 49±14 years, body mass index 29±6 kg/m², FEV1 2.21±0.79 L). The group ≤3 years presented statistically higher spirometric values and exercise capacity compared to the group >3 years even after analysis of covariance adjustments for age, body mass index, disease control, and treatment duration (forced vital capacity 3.39 [3.09-3.70] L vs. 2.93 [2.59-3.26] L, p=0.048; FEV1 2.40 [2.17-2.63] L vs. 2.00 [1.75-2.25] L, p=0.023; 6-min walk test 567 [536-599] vs. 519 [484-554] m, respectively, p=0.048). All the other variables were similar between groups (p>0.05 for all).
conclusionParticipants who used inhaled corticosteroids for more than 3 years exhibited worse pulmonary function and exercise capacity. Despite this, exacerbation history, disease control, quality of life, anxiety, depression, and dyspnea in daily life, among other physical functional outcomes, were similar between short- and long-term use of inhaled corticosteroids in adults with asthma.
