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

Epstein-Barr virus (EBV) is an etiologic agent of endemic Burkitt lymphoma (BL), a prevalent pediatric cancer in sub-Saharan Africa. There are two known types of EBV, EBV Type-1 (EBV-1) and EBV Type-2 (EBV-2), both found in eBL patients. To determine the EBV load and type dynamics within the tonsils, saliva, whole blood, and plasma, we enrolled 102 children aged 1-14 undergoing tonsillectomy in a malaria holoendemic region of western Kenya. Additionally, we investigated EBV-2 cell type preference in tonsillar mononuclear cells (TMCs). Saliva, whole blood, and tonsillar tissue were collected at the time of enrollment. Whole blood was centrifuged to separate plasma from red blood cells, and tonsillar mononuclear cells (TMCs) were isolated from tonsils using a ficoll gradient. Using qPCR, we assessed EBV load and type in TMCs, plasma, whole blood, and saliva. Additionally, a subset of samples was subject to cell sorting to determine the infected cell population. We found that EBV loads were significantly higher in TMCs compared to whole blood (
