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

aimsAmisulpride, a first-line schizophrenia treatment, has shown large interindividual variability in plasma/serum levels, often outside the reference range (100-320 ng/mL). This study aims to clarify the impact of dose, sex, age and related factors for the interpatient variability in amisulpride plasma/serum concentration.

methodsBoth English and Chinese databases were searched from their inception to May 16, 2019, using the terms: amisulpride and (plasma OR serum OR blood OR "drug monitoring" OR concentration). Studies reporting concentrations and either a dose, associated factor, clinical outcome or side effect were included.

resultsFourteen studies with 1628 participants were eventually included. Eligible articles yielded data on drug concentration and dose, averaging 333.9 (95% confidence interval [CI]: 294.5-373.3) ng/mL and 636.2 (95% CI: 549.7-722.6) mg/d, respectively. The calculated mean concentration-to-dose (C/D) ratio was 0.60 (95% CI: 0.52-0.67) (ng/mL)/mg. Subgroup analysis suggested that female patients on combined lithium-amisulpride have higher concentration levels and C/D ratios. Age was slight positive associated with C/D ratio while not for plasma level. Smoker patients have high concentration level than nonsmoking patients but not for C/D. Responsive and nonresponsive groups did not differ in concentration and C/D.

conclusionPooled concentration levels of amisulpride were higher than recommended with wide individual variation, especially in older patients, female patients and patients taking amisulpride combined with lithium. The specific therapeutic reference range for amisulpride may require reconstruction, which should consider the influence of age, sex, kidney function, drug-drug interactions, different dose regimens and sampling times in future study.
