Article in European clinical respiratory journal, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 18 papers, 1 of them a synthesis that pooled it.

1 · What the graph read from 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.

2 · The registry

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

introductionIdiopathic pulmonary fibrosis (IPF) is a chronic disease with high morbidity and mortality. A reliable and manageable questionnaire that assesses patients' quality of life is needed to help to improve the content of clinical consultations. The chronic obstructive pulmonary disease (COPD) Assessment Test (CAT) is used in clinical practice; therefore, the aim of this study was to investigate correlations among the CAT, St. George's Respiratory Questionnaire (SGRQ) and clinical parameters among patients diagnosed with IPF.
