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

Human herpesvirus 8 (HHV-8) is the etiologic agent of Kaposi's sarcoma (KS), primary effusion lymphoma (PEL), multicentric Castleman disease (MCD), and KS-associated immune reconstitution inflammatory syndrome (IRIS-KS). Quantifying HHV-8 DNA in whole blood is clinically relevant, yet laboratory practices remain heterogeneous. Here, we developed and validated an in-house quantitative PCR (qPCR) assay targeting ORF26, optimized for whole blood. Assay calibration used plasmid, BCBL-1 cell-derived, and commercial HHV-8 DNA standards. Analytical validation was performed following the Clinical and Laboratory Standards Institute (CLSI) guidelines and the Minimum Information for Publication of Quantitative Real-Time PCR Experiments (MIQE) guidelines and showed a 95% limit of detection of 65.7 copies/reaction, efficiencies of 90-101% (R
