Molecular characterization of hepatitis A virus from children hospitalized at a tertiary care centre in northwest India.
Article in The Indian journal of medical research, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Background & objectives: Hepatitis A virus (HAV) infection is a major cause of childhood hepatitis, prevalent worldwide. HAV is classified into seven genotypes I-VII; genotypes III and I are the most common among humans. The present work was carried out to identify the genotypes prevalent in children suspected to have acute viral hepatitis (AVH), hospitalized at a tertiary care centre in northwest India. Methods: A total of 1269 blood samples from children (0-15 yr of age) clinically suspected of viral hepatitis were screened for anti-HAV IgM. Acute phase serum was processed for RNA extraction and amplified by nested polymerase chain reaction (PCR) followed by sequencing of representative samples. Results: Among the 1269 samples tested, 642 (50.59%) were positive for anti-HAV IgM; among the positive samples, 171 patients having a history of less than seven days were tested by PCR, of whom 141 (82.45%) were found to be PCR positive. Nucleotide sequencing of a representative 44 samples showed high homology; all the samples were found to be of genotype IIIA. Interpretation & conclusions: Hepatitis A was prevalent during July to September and in predominantly children less than five years age. Only genotype IIIA was detected in all the samples.
