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

A woman living with HIV reported swallowing difficulties that interfered with oral antiretroviral therapy. Treatment with darunavir/cobicistat/emtricitabine/tenofovir alafenamide (Symtuza®) was initiated, with the patient choosing to chew the tablet before swallowing because of her swallowing difficulties. Therapeutic drug monitoring, performed because of this non-standard administration, revealed unexpectedly low darunavir trough concentrations despite reported adherence and maintained virological suppression. A structured pharmacological assessment revealed that the patient had been consistently taking the medication in the fasting state, despite initial counselling to take it with food. After correction of the drug intake conditions, darunavir exposure increased to therapeutic levels. This case highlights the clinical value of therapeutic drug monitoring in identifying medication intake errors and optimising antiretroviral therapy in patients with swallowing difficulties.
