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
Background: Despite global efforts to improve equitable access to healthcare, underserved and mobile populations in Sub-Saharan Africa continue to face major challenges in obtaining essential medicines and vaccines. In Tanzania, Artisanal miners, fisherfolk, and pastoralists face high disease burdens, mobility, and geographic isolation, yet evidence on their access to essential medicines and vaccines remains limited. This study examined access to essential medicines and vaccines among artisanal mining, fishing, and pastoralist populations in Tanzania. Methods: A descriptive cross-sectional study was conducted in six selected districts of Manyara, Mara, and Geita regions, representing pastoralist, fisherfolk, and artisanal mining communities, respectively. A semi-structured questionnaire was administered to 280 conveniently sampled community participants and to 29 purposively selected pharmacists or drug dispensers. Data were analysed using descriptive statistics and chi-square tests with support of STATA software. Results: Availability of essential medicines was limited, with 58.1% of participants reporting that they did not obtain all prescribed medicines during their most recent treatment episode. Vaccine availability was reported as always available by 65.0% of participants, while 24.6% were uncertain. Regarding affordability, 51.3% reported spending over TZS 10,000, 39.0% could not afford prescribed medicines. In terms of accessibility, 40.3% lived within 1-5 km of a health facility, and 62.8% lived within 1 km of a pharmacy or drug outlet. Acceptability indicators showed that 86.7% trusted healthcare providers and 81.7% adhered to treatment, while 59.3% lacked to the knowledge on identify counterfeit medicines. Overall, 92.0% reported improvement after treatment, and 31.0% of providers reported occasionally receiving complaints about the quality of the medicine. Conclusions: While vaccine access appears well established, significant gaps remain in ensuring equitable access to essential medicines in these populations. Addressing supply chain inefficiencies, financial barriers, geographic constraints, and patient awareness, is critical for advancing equitable access and achieving universal health coverage.
