Clinical Severity of Enteric Viruses Detected Using a Quantitative Molecular Assay Compared With Conventional Assays in the Global Enteric Multicenter Study.
Article in The Journal of infectious diseases, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundQuantitative molecular assays are increasingly used for detection of enteric viruses.
methodsWe compared the clinical severity using the modified Vesikari score (mVS) of enteric viruses detected by conventional assays (enzyme immunoassays [EIAs] for rotavirus and adenovirus 40/41 and conventional polymerase chain reaction for astrovirus, sapovirus, and norovirus) and a quantitative molecular assay (TaqMan Array Card [TAC]) among children aged 0-59 months in the Global Enteric Multicenter Study. For rotavirus and adenovirus 40/41, we compared severity between EIA-positive and TAC-positive cases assigned etiologies using different cycle threshold (Ct) cutoffs.
resultsUsing conventional assays, the median mVS (interquartile range) was 10 (8-11) for rotavirus, 9 (7-11) for adenovirus 40/41, 8 (6-10) for astrovirus, sapovirus, and norovirus GII, and 7 (6-9) for norovirus GI. Compared with rotavirus EIA-positive cases, the median mVS was 2 and 3 points lower for EIA-negative/TAC-positive cases with Ct <32.6 or Ct ≥32.6 and <35, respectively (P < .001). Adenovirus 40/41 EIA-positive and EIA-negative/TAC-positive cases were similar, regardless of Ct cutoff.
conclusionsQuantitative molecular assays compared with conventional assays, such as EIA, may influence the severity of identified cases, especially for rotavirus. Cutoffs to assign etiology for quantitative assays should be considered in the design and interpretation of enteric virus studies.
