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
Introduction: Post-bronchodilator (BD) spirometry testing is required for a diagnosis of airflow obstruction (AO) and COPD. We compared the impact of pre- and post-BD AO, as well as that of pre-BD and post-BD reference values, on survival, exacerbations, and FEV Methods: We analyzed data derived from the Proyecto Latinoamericano de Investigación en Obstrucción Pulmonar (PLATINO, Latin American Project for the Investigation of Obstructive Lung Disease) study, involving individuals residing in three Latin American cities and evaluated 5-9 years after baseline examination. Categories were formed by pre-and post-BD FEV Results: At baseline, 2,942 participants completed pre- and post-BD spirometry; 2,262 were normal (controls); 139 had pre-BD AO (FEV Conclusions: Individuals with post-BD AO identified only with post-BD reference values had an increased risk of death. Those with pre-BD AO had higher mortality and an increased risk of developing COPD, therefore requiring close follow-up monitoring and being classified as pre-COPD patients.
