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
backgroundAcute exacerbation (AE) of idiopathic pulmonary fibrosis (IPF) has the most disastrous impact on prognosis as a major cause of morbidity and mortality. However, there is no proven treatment, and the occurrence of AE is unpredictable. This study aimed to develop a prediction model for AE in patients with IPF using the nationwide Korea IPF Cohort (KICO) registry.
methodsThis is a retrospective study of Korean patients with IPF who were enrolled from June 2016 to February 2022 in the KICO registry. We developed a prediction model for AE based on risk factors found in the multivariable logistic regression model.
resultsOf 678 patients with IPF, the mean age was 69.4 years, and 82.0% were male. AE occurred in 165 patients (24.3%) during follow-up (median: 40.7 months). The median time from IPF diagnosis to AE was 11.6 (interquartile range: 3.6-23.5) months. Lower forced vital capacity (FVC), shorter six-minute walking distance (6MWD), and the use of home oxygen were independently associated with AE in the multivariable logistic analysis. In a risk-predicting model using variables of FVC, 6MWD, and the use of home oxygen, there was a significant predictive power for AE in both score (area under the curve [AUC], 0.746; 95% confidence interval [CI], 0.705-0.783;
conclusionOur results suggest that a model using FVC, 6MWD, and home oxygen use may be useful in predicting AE in patients with IPF.
