1 · What the graph read from it

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.

2 · The registry

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

objectiveTo identify risk factors for severe pertussis and assess the efficacy of exchange transfusion in children.

methodsWe analyzed pediatric pertussis cases, comparing mild and severe presentations using hospital data on demographics, symptoms, lab findings, echocardiography, and complications, and employed ROC analysis to determine severe pertussis risk factors.

resultsOur study analyzed 119 mild and 64 severe pertussis cases, with severe cases characterized by earlier onset, spasmodic cough, shortness of breath, and rales. Risk factors for severity included lack of DTaP vaccination and pulmonary hypertension. Severe cases also showed higher WBC and lymphocyte counts and more mixed infections. Logistic regression identified shortness of breath, no DTaP, younger age, and high WBC as severity predictors (P < 0.05). ROC analysis predicted severity with age < 3.68 months and WBC > 27.93 × 10

conclusionClinicians should closely monitor unvaccinated children with shortness of breath, onset before 3.68 months, and WBC > 27.93 × 10 IMPACT: This study delineates four key predictors of severe pertussis in children: younger age, lack of DTaP vaccination, shortness of breath, and elevated white blood cell (WBC) counts. We establish WBC > 27.93 × 10
