Correlation of prognostic values of IL-6 and PCT levels with the severity of pneumonia caused by
Article in Pakistan journal of medical sciences, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Objective: To explore the correlation of interleukin 6 (IL-6) and procalcitonin (PCT) with severity of Methods: One hundred twenty children with MPP and 100 healthy children who underwent physical examination at the Clinical Laboratory Department of Nantong University Maternal and Child Health Hospital from November 2023 to December 2023 were selected as the study subjects, and were divided into the experimental group and the control group. The experimental group was divided into mild MPP group (n=70 ) and severe MPP group (n=50 ) according to the severity of the disease. According to the condition after one course of treatment, separated MPP children into good prognosis group (n=96) and poor prognosis group (n=24). The IL-6 and PCT levels of the experimental/control group before treatment and the good/bad prognosis group after treatment were compared, respectively. The lung function of children with MPP before and after treatment was also examined, and the changes of respiratory rate (RR), tidal volume (VT), expiratory time (Te), peak time (TPTEF), and peak volume (VPTEF) were observed. The correlation between pulmonary function and IL-6, PCT in MPP children was analyzed by Pearson analysis. Receiver operation curve was adopted to analyze the predictive value of IL-6, PCT for poor prognosis. Results: IL-6 and PCT were increased in the severe MPP group compared to the mild MPP group (P<0.001) and tended to decrease in the good prognosis group compared to the poor prognosis group (P<0.001). Fifty-nine of the 70 cases in the good prognosis group were patients with mild MPP, suggesting that patients with mild MPP have a better prognosis. The results of respiratory function showed an increase in RR (P<0.001) and a decrease in VT (P=0.007), TPTEF/Te (P<0.001), VPTEF/VT (P<0.001) in the severe MPP group compared to the mild MPP group. The results of correlation analysis revealed that IL-6, PCT were negatively correlated with VT, TPTEF/Te and VPTEF/VT (P<0.001). ROC curve analysis revealed that IL-6 and PCT co-diagnosis had a better predictive ability for poor prognosis in children with MPP (AUC=0.843). Conclusion: IL-6 and PCT are positively related to the severity of MPP, the combined detection of IL-6 and PCT has certain clinical usefulness to evaluate and assess prognosis of MPP children.
