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

backgroundCytokines are critical biomarkers, but their accurate measurement is susceptible to pre-analytical variables. This study investigated the effect of delayed blood processing on the quantitation of eight cytokines (CCL2, CXCL10, IFN-γ, IL-2Ra, IL-6, IL-7, IL-18, TNFα) in matched serum and plasma from healthy volunteers. Methods: Blood was processed immediately or after 3, 6, 24, and 48 hours, stored at room temperature or 4°C. Cytokines were quantified using a multiplexed Ella assay.

resultsOur data showed only IL-2Ra remained stable across all conditions. The remaining cytokine concentrations were significantly impacted by processing delay and storage temperature, with changes evident as early as 3 hours and more pronounced at 24 and 48 hours (

conclusionThese findings emphasize delayed processing significantly alters cytokine levels, highlighting the importance of prompt, standardized processing and careful consideration of pre-analytical factors for reliable cytokine quantitation in clinical studies.
