The significance of periostin in the diagnosis of idiopathic pulmonary fibrosis and prediction of acute exacerbations.
Article in Journal of thoracic disease, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Background: This study aims to elucidate the capability of periostin (POSTN) as a serum biomarker in diagnosing idiopathic pulmonary fibrosis (IPF), assessing disease severity, and predicting acute exacerbations of IPF (AE-IPF), and to compare it with traditional IPF serum biomarkers Krebs von den Lungen-6 (KL-6), surfactant protein A (SP-A), and surfactant protein D (SP-D). Methods: From October 2022 to October 2023, 55 patients who were diagnosed with IPF and treated at the Third Affiliated Hospital of Anhui Medical University were enrolled in the IPF group. Additionally, 30 patients with bacterial pneumonia (BP) and 30 healthy individuals were selected as the BP and healthy control (HC) groups, respectively. All participants underwent pulmonary function tests, and enzyme-linked immunosorbent assay (ELISA) was used to measure serum POSTN, KL-6, SP-A, and SP-D levels. IPF patients also underwent high-resolution computed tomography (HRCT) to quantify HRCT scores. Receiver operating characteristic (ROC) curves were plotted to obtain sensitivity and specificity. Binary logistic regression analysis was conducted to identify AE-IPF risk factors. Results: Serum POSTN, KL-6, SP-A, and SP-D concentrations were significantly greater in the IPF group than in the BP and HC groups (P<0.001), whereas serum SP-A and SP-D levels were greater in the BP group than in the HC group (P=0.001, P=0.04). The sensitivity of POSTN for diagnosing IPF is 94.5%, and the specificity is 93.3%, both of which are higher than those of KL-6, SP-A, and SP-D. Within the IPF group, serum POSTN levels were negatively correlated with the percentage of predicted forced expiratory volume in one second (FEV Conclusions: POSTN is a valuable serum biomarker for IPF and has the highest sensitivity and specificity among the four serum markers, with a diagnostic performance superior to that of KL-6, SP-A, and SP-D. DLCO%pred and KL-6 have high predictive value for AE-IPF.
