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

Background/aim: Patent and Proprietary Medicine Vendors (PPMVs) are major private and informal healthcare service providers in Nigeria, whose activities are regulated by the Pharmacy Council of Nigeria (PCN). Review of literature have documented concerns about PPMVs' non-compliance with PCN's service provision guidelines and their implications for the health outcomes of their clients. Studies among PPMVs on the services they provide and their non-compliance with regulatory guidelines in semi-urban areas have been under explored. This study however, investigated types of services provided by PPMVs and their non-compliance with regulatory guidelines in Ibadan, Oyo State, Nigeria. Materials/methods: This descriptive cross-sectional study included registered patent and proprietary medicine vendors selected from two out of the six semi-urban Local Government areas of Ibadan, Oyo State through random sampling using an interviewer-administered semi-structured questionnaire with data collected using the KoboCollect. The questionnaire elicited responses on the types of services provided by PPMVs to their clients and factors influencing their non-compliance with the regulatory guidelines. Data was collected and analysed using descriptive and inferential statistics with SPSS version 25, at 0.05 level of significance. Results: Two hundred and eight respondents were recruited for the study. Respondent's mean age was 38.17-10.82, years. Majority (80.8%) were females, less than half (40.9%) had post-secondary-level education. A few (13.9%) had additional health-related qualifications. Respondents provided services which were both within (treatment of ailments; 50.5%, and Referral 50%) and outside (giving injections; 51.9% and prescription of medicine; 49.1%) their scope of operation. Factors which influenced non-compliance mentioned by respondents were attendance of PCNs training, licensure with PCN and reception of monitoring visits, were significantly associated with noncompliance with guidelines on service provision (p<0.05). Conclusion: Patent and proprietary medicine vendors in Ibadan, Oyo state, play a significant role in providing accessible primary healthcare services within and outside their scope of operation to the populace, several factors are responsible for their non-compliance with regulatory guidelines which dove-tailed into rendering of services beyond their scope of operations.
