Epidemiology of Pertussis and the Screening Value of WBC and Lymphocyte Percentage.

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: Pertussis is a highly contagious respiratory disease, and early diagnosis and timely treatment are crucial for reducing complications and transmission. In this study, we analyzed the prevalence of pertussis and assessed the value of the WBC and lymphocyte percentage in its screening. Methods: A retrospective analysis was conducted on global pertussis data from the past decade. Patients who recently underwent pertussis nucleic acid detection and complete blood count (CBC) in our hospital were selected. Based on the results, 538 patients were classified into the pertussis group, and 595 into the control group. White blood count (WBC) and lymphocyte percentages were compared, diagnostic efficacy was calculated, and evaluate their application value in the diagnosis of pertussis. Results: In the past decade, the global incidence of pertussis first decreased, then increased. In China and Zhejiang province, it fluctuated but showed an upward trend recently. In Zhejiang Province, pertussis was more prevalent in summer and winter and rose last year. Between 2018 and 2020, most pertussis cases in China were infants under 1 year old. Last year, only 1.12% of patients in our hospital were infants, with more patients over 5 years old. WBC, lymphocyte percentage, and platelet count (PLT) was higher in the pertussis group (P < 0.05). Logistic regression showed that WBC, lymphocyte percentage, and PLT were correlated with pertussis infection. Sequential analysis showed that the WBC, lymphocyte percentage, and Youden's index for both combined were 0.124, 0.082, and 0.044, respectively. Conclusion: The global incidence of pertussis is rising, with significant increases among adolescents and adults. Improved prevention and control strategies are needed. WBC and lymphocyte percentage serve as auxiliary diagnostic indicators, but their efficacy is limited.
