Socioeconomic deprivation and its association with polypharmacy in England: results from a national cross-sectional survey.
Article in International journal of clinical pharmacy, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
introductionPolypharmacy is a growing public health concern, yet its association with area-level socioeconomic deprivation in England has been under-explored.
aimTo investigate whether socioeconomic deprivation, measured by the Index of Multiple Deprivation (IMD), is associated with polypharmacy among adults.
methodWe analysed cross-sectional data from the 2021 Health Survey for England, including 1705 adults aged 16+ who completed nurse visits and reported prescribed medication use in the past week. Polypharmacy was defined as the use of five or more prescribed medications. IMD scores were categorised into quintiles (least to most deprived). Multivariable logistic regression estimated adjusted odds ratios (ORs) with 95% confidence intervals (CIs), controlling for age, sex, ethnicity, multimorbidity, obesity, smoking, alcohol use, and GP visit frequency. A polynomial contrast test assessed linear trends, and adjusted predicted probabilities were calculated to illustrate the deprivation-polypharmacy gradient.
resultsIn the fully adjusted model, adults residing in the most deprived IMD quintile had significantly higher odds of polypharmacy (OR 1.82; 95% CI 1.09-3.04; p = 0.022) compared to those living in the least deprived areas. No statistically significant associations were observed for intermediate quintiles. A polynomial contrast test confirmed a significant linear trend across IMD levels (p = 0.010), indicating that the odds of polypharmacy increased progressively with greater area-level deprivation. This gradient was further illustrated by adjusted predicted probabilities, which rose from 18.3% (95% CI 15.3-21.3%) in the least deprived quintile to 24.6% (95% CI 20.1-29.2%) in the most deprived (p < 0.001).
conclusionSocioeconomic deprivation is independently associated with polypharmacy, even after adjusting for multimorbidity and other confounders, highlighting persistent health inequalities within England's healthcare system. Targeted strategies, including regular medication reviews and enhanced access to care in deprived communities, may help mitigate risks and promote equity in prescribing practices.
