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
Intravenous immunoglobulin (IVIG) therapy is a well-documented and effective treatment for primary immunodeficiencies (PI). Subcutaneous immunoglobulins (SCIG) have emerged as an effective alternative for some patients that offers additional flexibility.Currently, caprylate/chromatography purified IGSC (human) 20% is approved to treat PI in North America and many countries worldwide. In this multi-center, open-label study, the pharmacokinetics (PK), efficacy, and safety of IGSC 20% were studied after biweekly (every two weeks) dosing for 16 weeks and compared to weekly IGSC 20% administration for 16 weeks in treatment-experienced PI patients. A loading/weekly maintenance SC regimen was also studied in PI patients naïve to IG treatment.In treatment-experienced patients, the least squares mean ratio of steady-state AUC0−7 days for biweekly dosing showed non-inferiority to weekly dosing (90% confidence interval 1.0030–1.0685). Other PK parameters (Cmax, Tmax, steady state trough) were similar between treatments. Efficacy and safety measures were qualitatively similar to previously published results. No serious bacterial infections were reported. Annual rates for any type of infection were similar between the treatment groups. All severe treatment-related adverse events (AEs) were unrelated to treatment. Only mild to moderate suspected adverse drug reactions were observed.PK analyses showed that biweekly dosing of IGSC 20% was non-inferior to weekly dosing in treatment-experienced PI patients. Biweekly dosing had similar patterns to weekly in prevention of serious bacterial infections, rates of all infections and hospitalizations for infections. The IGSC loading/maintenance dosing regimen in naïve patients was safe and effective during the observation period.
