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

backgroundThe 2018 European Society of Cardiology (ESC)/European Society of Hypertension (ESH) guidelines for the management of hypertension highlight the importance of fixed-dose combinations (FDC) for the treatment of hypertension and recommend initial single-pill combination therapy in almost all patients. However, data on the implementation of these recommendations in clinical practice are scarce.

methodsData from the German Institute for Drug Use Evaluation (DAPI) were analyzed and extrapolated accounting for approximately 88% of Germany's population (approximately 73.3 million subjects). All antihypertensive (AHT) FDC products available on the German market were included in the analyses. We examined the time course of dispensed packages between January 2016 and December 2020.

resultsFDCs accounted for 15.4% of all AHT in 2016 and for 10.9% in 2020. While dispensing of all AHT increased slightly from year to year (2016: 143.8 million, 2020: 153.2 million packs), dispensing of FDCs decreased from 22.2 million (2016) to 16.6 million (2020) packs. Dispensing of FDCs containing hydrochlorothiazide (HCT) declined considerably from 2016 to 2020 (Q1 2016: 4.65 million, Q4 2020: 3.13 million packs). Accordingly, the proportion of HCT-containing combinations in all FDCs decreased from 85.3 to 74.2% from Q1 2016 to Q4 2020. Patients younger than 80 years were prescribed FDCs more frequently (14.6% of all AHT, based on the entire evaluation period) than patients 80 years and older (10.0%). In both age groups, this proportion decreased continuously over time.

conclusionsAlmost 2 years following the release of the 2018 ESC/ESH guidelines, only 10.9% of the prescribed packs of antihypertensive drugs in 2020 were FDC products, documenting underutilization of current guideline recommendations on pharmacotherapy in hypertension. Structured programs to evidence-based decision support are required to improve guideline inertia and patient outcomes, eventually.
