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

backgroundIn Nigeria, patent and proprietary medicine vendors (PPMVs) are permitted to sell a limited range of medication. They are important providers of health care despite their limitations and may be trained to manage specific conditions, such as malaria, but not ear and eye conditions. In this study, PPMV's knowledge and management of ear and eye problems and community members health seeking behaviour were explored, as well as whether community members would access PPMVs if they were trained in primary ear and eye care.

methodsQuantitative and qualitative methods were used in a cross-sectional observation study: a survey of 1,591 adults in 40 clusters in two urban and two rural areas; 64 focus group discussions with community members and four with health professionals in two ear, nose, throat and eye clinics; in-depth interviews with ten community leaders, 11 primary health care workers, and 21 hospital staff. A check list was used to assess 36 PPMVs' facilities and structured questionnaires were administered to 36 PPMVs and 401 hospital patients in ear and eye outpatient departments.

resultsCommunity members reported that eye and ear problems were frequent but less common than other conditions. Health seeking behaviour was influenced by accessibility, availability, cost of medication, and trust in the provider. Most PPMVs had no formal training, had little knowledge of ear and eye conditions and were enthusiastic about being trained to manage them. Living far (>5km) from a health facility, being male, uneducated and poor were significantly associated with willingness to access PPMV after training in primary ear or eye care.

conclusionsPPMVs might be able to play a role in delivering primary ear and eye health care for common conditions, in collaboration with local clinicians. To do this, PPMVs would require training in eye and ear conditions and skills in their detection and counselling clients as well as reliable supply chains for medication, and skills in stock control, record keeping and facility management.
