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
Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a debilitating disease with unknown etiology and heterogeneous symptomology for which there are no validated tests for definitive diagnosis. We examined 873 longitudinal serum samples from ME/CFS patients (n = 40) and 378 from healthy control individuals (n = 16) for differences in human herpesvirus and endogenous retrovirus-K (HERV-K) dUTPase IgG antibodies by ELISA. The results of this study demonstrate a significant increase in dUTPase IgG antibodies to the herpesviruses Epstein-Barr virus (EBV), human herpesvirus-6 (HHV-6) and varicella zoster virus (VZV) in ME/CFS compared to healthy-controls (p < 0.001). Notably, 72.5% (n = 29) of ME/CFS patients simultaneously co-expressed antibodies to multiple herpesvirus and HERV-K dUTPases compared to 31% (n = 5) of the healthy controls. Chi-square test analysis showed strong associations for EBV, HHV-6 and VZV dUTPase antibodies seropositivity (p < 0.001) and Spearman correlation analysis revealed significant positive associations of EBV and HHV-6 dUTPase IgG antibodies with fatigue. Further examination of the distribution of dUTPase antibodies across fatigue severity groups show that heightened dUTPase IgG levels cluster with ME/CFS patients exhibiting moderate and severe fatigue. These findings highlight the importance of examining herpesvirus dUTPase IgG across severity groups in aiding with current challenges for stratifying ME/CFS patients due to the heterogeneity in symptomology.
