Drug-drug interactions and inappropriate medicines impact on glycemic control and kidney function in older adults with diabetes-attending specialty care institution.
Article in European journal of clinical pharmacology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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
purposeTo describe and assess the impact of polypharmacy, and its potential adverse reactions; serious clinically relevant drug-drug interactions (DDIs) and inappropriate medicines (PIMs) on glycemic target, and kidney function in a sample of older adults with type 2 diabetes (T2D).
methodsCross-sectional study was performed in a real-world database including 444 elderly people with T2D from the Portuguese Diabetes Association, aged ≥ 65 years, and registered in 2018. DDIs were analyzed using Micromedex drug-interaction platform and PIMs identified using STOPP criteria version-2.
resultsPolypharmacy was identified in 43.6% of patients. This group of patients has shown to be more females (50 vs. 39.6%, P=0.0208), higher HbA1c targets (P=0.0275), longer diabetes duration (66.4 vs. 54.4%, P=0.0019), more hypertensive (87 vs. 62.9%, P<0.0001), using more insulin (38.1 vs. 26%, P=0.0062), sulfonylureas (37.1 vs. 15.6%, P<0.0001), GLP-1 receptor-agonists (9.7 vs. 3.6%, P=0.0077), metformin-DPP-4 inhibitors (41.2 vs. 29.2%, P=0.0081), and SGLT2 inhibitors (19 vs. 9.6%, P=0.0040). A total of 8.7% of patients had potentially serious clinically relevant DDIs, mainly due to interacting medicine pairs dexamethasone and fluoroquinolones. Furthermore, 23.4% had PIMs, and cardiovascular medicines accounted for largest therapeutic group associated. Polypharmacy found to be associated with twofold greater odds of having HbA1c ≤8%, whereas PIMs associated with 2.5-fold greater odds of having HbA1c ≤9%, and 5.5-folds greater odds of having severe kidney function.
conclusionsThese findings suggested that there is a potential association between polypharmacy and PIMs and altered glycemic control, and PIMs with the deterioration of kidney function.
