Clinico-Epidemiological Profile of Pediatric Diphtheria Cases in a Tertiary Care Hospital in Western India: A Cross-Sectional Study.

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
backgroundDiphtheria is an acute, fatal, bacterial toxin-induced disease and a significant health problem in developing countries. It remains endemic in India, including the state of Rajasthan. MATERIALS AND
methodsThe present study was a cross-sectional observational study conducted in a tertiary care center of Western India (Jodhpur, Rajasthan) over a period of one year (January to December 2019). All patients in the pediatric age group (up to 18 years of age) who presented with clinical features of suspected diphtheria per the WHO case definition and a positive throat swab for Klebs-Löffler bacillus (KLB) stain were enrolled in the study.
resultsA total of 21,146 patients in the pediatric age group were admitted during the study period, out of which 66 fulfilled the inclusion criteria. The proportion of diphtheria was 3.121 per 1,000 admissions, with the highest number of cases admitted in the winter season from November to February 2019 (42, 63.64%). The male-to-female ratio was 1.87:1, and most cases were from lower socioeconomic strata (43, 65.15%), resided in rural areas (57, 86.36%), were partially immunized (42, 63.64%), and belonged to the 6-14 years age group (49, 74.24%). Most cases presented with pseudomembrane (64, 96.97%), followed by fever (60, 90.91%), dysphagia (57, 86.36%), and neck oedema (51, 77.27%). The most common complications were myocarditis (23, 34.85%), followed by polyneuropathy (17, 25.76%), acute kidney injury (16, 24.24%), bleeding diathesis (15, 22.73%), and multiple organ dysfunction syndrome (MODS) (11, 16.67%). Thrombocytopenia, high levels of blood urea, serum sodium and potassium, and creatine kinase-myocardial band (CK-MB) were significantly associated with poor outcomes, and 23 cases (34.84%) had abnormal ECG findings suggestive of myocarditis. The case fatality rate (CFR) was 18.18% (12/66), ranging from 11.90% among partially immunized cases to 33.33% among unimmunized children.
conclusionHigh immunization coverage for diphtheria among children under five years of age has shifted the age group to 6-14-year-old children who are less immune to the disease. Biochemical parameters such as low platelets, high blood urea, serum sodium and potassium, and raised serum CK-MB are associated with poor outcomes. Myocarditis also carries a poor prognosis.
