Visual assessment of antimicrobial medicine packaging and labeling quality in pharmacies of Ho Municipality, Ghana.
Article in PloS one, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundSubstandard and falsified antimicrobials threaten public health due to their role in resistance development. Pharmacies, as key access points for antimicrobials, can play a crucial role in detecting these products. In this study, a visual assessment tool which incorporates a novel packaging quality index estimate, was developed and used in pharmacies to evaluate antimicrobial packaging and flag suspicious products.
methodsA cross-sectional study was conducted in 23 community pharmacies in the Ho Municipality between November 2023 and February 2024. The developed checklist contains indicators on registration compliance, language & medical information, batch information consistency, and product security of the antimicrobials. The tool was validated, and its use on randomly sampled antimicrobials informed the development of the packaging quality index from regression analysis involving weights determined from principal component analysis of the results. Statistical analyses were performed with SPSS (version 26.0) and OriginPro (version 2022).
resultsThe packages and labels of the 275 antimicrobials evaluated were antibacterials (41%), antiprotozoals (28%), antifungals (22%) and antivirals (9%). Most products were of foreign origin (58.5%) and labelled in English (98%). Significant variations were observed in the registration compliance and product security indicators by origin and antimicrobial class (p < 0.01). Batch information consistency varied significantly across the antimicrobial classes (p < 0.01), whereas language & medical information quality remained consistent. The packaging quality index scores followed a normal distribution, with majority (95.6%) referred to as moderate quality (Index: 1.81-5.34). High quality packages (2.2%; Index: 5.47-5.53) were mostly observed in antibacterials of local origin (66.7%) whereas the poor-quality packages observed (2.2%; Index: 1.48-1.78) were mostly antibacterials of foreign origin (66.7%).
conclusionThis study identified packaging quality issues among the antimicrobials investigated which may suggest potential risk to falsification. Routine antimicrobials packages assessment with developed tools like the packaging quality index could help pick up early signals of substandard and falsified antimicrobials for further regulatory investigations and action.
