The Role of Epstein-Barr Virus in Adenoid and Tonsil Enlargement in Nigerian Children.
Review in Nigerian medical journal : journal of the Nigeria Medical Association. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: Epstein-Barr Virus (EBV) is a lymphotropic virus that persists in lymphoid tissues such as the adenoids and tonsils and has been associated with several head and neck diseases. Because adenotonsillar enlargement is common in children, this study investigated whether EBV contributes to hypertrophy of these tissues. Methodology: A comparative cross-sectional study was conducted at the University of Abuja Teaching Hospital involving 90 age and sex-matched children, 45 test and 45 control. Adenoid size was assessed radiologically using the Fujioka Adenoid-Nasopharyngeal Ratio (ANR), tonsil size was graded with the Brodsky system, and EBV status was determined using Chemiluminescence Immunoassay. Postoperative tissue volumes were also measured. Results: Ninety children (test: 45; control: 45) participated; groups were age- and sex-matched (p = 0.480). Mean ages were 51.7±5.4 months (test) and 66.5±5.6 months (control). Mean Brodsky grade was 2.80±0.99, and mean ANR was 0.72±0.21.EBV IgG prevalence for the test group was 91.1% and 8.9% were EBV negative prevalence, and 82% with 17% for control respectively. There was also a significant difference between the mean values of the EBV IgG titers in the test and control groups using the T-test analysis. T= 12.956, p= <0.001. The Odds ratio was 2.6. Only two (2) patients in the test group tested positive for EBV IgM and IgG. There was a positive correlation between EBV status and tonsil volume p=0.0320, r =0.320 and Brodsky grade r= 0.338 p= 0.023. However, the adenoid volume and ANR showed a weaker correlation with the EBV status of the test patients p= 0.466, r= 0.113. Conclusion: These findings suggest that EBV may be associated with the development and progression of
