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

Real-time polymerase chain reaction (PCR) is the current standard for serum HBV DNA measurement. However, conventional real-time PCR assays have technical limitations, and are not sensitive enough to detect low-level residual viremia in chronic hepatitis B (CHB) patients. We developed and validated a droplet digital PCR (ddPCR) assay for high-sensitivity detection of serum HBV DNA. A ddPCR assay was developed on the QX200 ddPCR System (Bio-Rad) for detection of serum HBV DNA in 200 μL of serum. The primers and probe were designed to target a highly-conserved region in the HBV X gene. The AcroMetrix HBV Panel (Thermo Fisher Scientific) and CHB patient samples were used for validation experiments to determine the assay sensitivity, specificity, linearity, intra-run variability, and inter-run variability. The ddPCR assay demonstrated lower limit of detection of 1.6 IU/mL and lower limit of quantification of 9.4 IU/mL for serum HBV DNA in probit regression. The assay also achieved excellent specificity (96.2%), linearity (R = 0.994, R
