[Medication-overuse and chronic headaches in Brazzaville: patients' profile and therapeutic approach].

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
introductionMedication-overuse headaches (MOHs) are the least studied of all headaches in Africa.
methodsWe conducted a longitudinal study in order to describe our experience with patients placed in Neurology Outpatient observation in Brazzaville over a period of 4 years, from September 2010 to August 2014. All patients with chronic primary headaches, according to the International Classification of Headache Disorders (ICHD) (2nd edition), were included in the study. All patient with secondary headaches or who hadn't given consent were excluded. The patients were divided into two groups: those who had progressed to medication-overuse and those who didn't meet the criteria for medication-overuse (without-MOH). The variables used were the sociodemographic characteristics of patients, the clinical features of primary headaches and MOH treatment.
resultsThe study population was constituted by 193 patients out of 212. The average age of patients was 42 ± 14 years, of whom 66.32% were women. MOH rate was 35.75%. The associated factors were: early age (p=0.003), concomitant use of nonsteroidal anti-inflammatory drugs (NSAIDs) and paracetamol (p=0.0001) as well as self-medication (p<0.0001). By contrast, higher education (p<0.0001) and the use of NSAID alone (0.002) were protective factors against the onset of MOH. Ambulatory withdrawal was the most practiced treatment and amitriptyline was the most commonly used medication.
conclusionMedication-overuse headaches are frequent in patients placed in Neurology Outpatient observation in Africa and deserve identification for a better management.
