Platelet Depletion Alters MCP-1 Measurements in Plasma From Children With Dengue.
Article in Journal of tropical medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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: Platelets are increasingly recognized as contributors to the cytokine storm in dengue, yet their residual presence in plasma may bias cytokine measurements. We compared MCP-1 levels between paired regular plasma (RP) and platelet-poor plasma (PPP) in children with dengue and evaluated how depletion influences cytokine quantification. Methods: We first conducted a systematic review of plasma isolation methods in pediatric dengue studies. We then collected paired RP and PPP from 16 hospitalized children with dengue (11 with warning signs and 5 with severe dengue). The PPP was obtained by double centrifugation and verified to contain < 10,000 platelets/μL. Absolute platelet counts were determined by flow cytometry using an antihuman CD41 antibody and bead-based quantification. After one freeze-thaw cycle, MCP-1 and IFN-γ (negative control for platelet secretion) were measured by cytometric bead array. Results: Among 167 reviewed articles, only 40% reported plasma isolation methods and 5% performed platelet depletion, with wide variability in centrifugation protocols. In our cohort, 63% of RP samples exceeded the platelet-poor threshold compared with only 10% of PPP after double-spin depletion. After effective platelet removal, MCP-1 levels increased nearly 5-fold in PPP versus RP ( Conclusion: Standard plasma isolation fails to consistently remove platelets, and subsequent depletion protocols can artifactually elevate the platelet-associated cytokines MCP-1. These findings underscore the need for standardized reporting of platelet depletion methods in dengue immunology research.
