SARS-CoV-2-specific humoral and cellular immunity assessment in Peruvian vaccinated population: a cross-sectional study.
Article in PeerJ, 2025. 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: Evaluating both humoral and cellular immunity is essential for optimizing vaccination strategies and preventing post-pandemic SARS-CoV-2 outbreaks. This cross-sectional study assessed cellular immunity by measuring Method: Whole blood samples were collected from 40 Peruvian volunteers. Results: The median age was 31 years, with 62.5% females. A heterologous vaccination scheme was reported by 73%, but only 25% received their last dose within the past 6 months, and 55% completed three doses. The BNT162b2 vaccine was included in 88% of vaccination schemes, serving as the first and second dose in 48% of cases. All participants had detectable anti-spike IgG antibodies; 90% exhibited cellular responses to Wuhan peptides and 97.5% to Omicron peptides. Conclusion: Most participants exhibited robust immunity, characterized by elevated levels of
