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

backgroundCost-effective use of biologicals is important. As drug concentrations have been linked to clinical outcomes, monitoring drug concentrations is a valuable tool to guide clinical decision-making. A concentration-response relationship for ustekinumab at trough is uncertain owing to the contradictory results reported.

objectivesTo investigate the relationship between 4-week postinjection ustekinumab concentrations and clinical response in patients with psoriasis.

methodsForty-nine patients with moderate-to-severe psoriasis treated with 45 mg or 90 mg ustekinumab every 12 weeks for ≥ 16 weeks were included. Ustekinumab serum concentrations and anti-ustekinumab antibodies were measured at week 4 after injection and disease severity was assessed by Psoriasis Area and Severity Index (PASI).

resultsAt week 4 after injection, a significantly negative correlation was observed between ustekinumab concentrations and absolute PASI score up to 5·9 μg mL

conclusionsA concentration-response relationship at week 4 after injection was observed for patients with psoriasis treated with ustekinumab. Monitoring 4-week postinjection ustekinumab concentrations could timely identify underexposed patients who might benefit from treatment optimization. What's already known about this topic? Monitoring drug concentrations is a valuable tool that can guide clinical decision-making when drug concentrations are linked to clinical outcomes. The presence of a concentration-response relationship for ustekinumab at trough is still debated owing to the contradictory results reported. What does this study add? A concentration-response relationship at week 4 after injection for ustekinumab-treated patients with psoriasis was demonstrated. Monitoring 4-week postinjection ustekinumab concentrations could timely identify underexposed patients who might benefit from treatment optimization. Based on the findings of this study, a treatment algorithm for patients with a suboptimal response is proposed.
