Development and validation of a clinical severity prediction model for hospitalized children with pertussis.
Article in BMC infectious diseases, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundTo explore the risk factors for severe pertussis and to develop a classification model for illness severity in hospitalized children with pertussis.
methodsA regression analysis was carried out on the cases diagnosed with pertussis in Wuhan Children's Hospital from January 2022 to October 2024. With April 2024 as the cut-off point, the patients were divided into a training group and a verification group. SPSS and R language were used to analyze the risk factors of severe pertussis in the training group and build a classification model for illness severity in hospitalized children with pertussis.
resultsAmong the relevant predictors, HR, RR, Moist rales, Hb, Alb and IgG are the independent risk factors for severe pertussis. In this study, a nomogram model for illness severity in hospitalized children with pertussis was constructed. Firstly, through training sets, it was confirmed that the prediction model had good discrimination (AUC = 0.935) and calibration (Mean squared error = 0.00062). Finally, the predictive value of the model was further confirmed in the internal validation sets as well (AUC = 0.93, Mean squared error = 0.00089).
conclusionThe nomogram constructed in this study provides a clinical tool for assessing severity stratification in hospitalized children with pertussis, guiding the early identification and clinical management of severe cases. CLINICAL TRIAL NUMBER: Not applicable.
