Prevalence and predictors of non-steroidal anti-inflammatory drug/analgesic therapeutic duplication in the South Korean ambulatory care setting.

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
purposeTherapeutic duplication (TD) in prescriptions is a common cause of inappropriate drug use. This study aimed to determine the prevalence of TD in the Korean ambulatory setting and to determine the patient and prescriber characteristics that were associated with TD of non-steroidal anti-inflammatory drugs (NSAIDs) and analgesics.
methodsAmbulatory care cases with NSAID/analgesic prescriptions were extracted from the National Health Insurance database for January–March 2011. The Korean TD classification (64 ingredients) was used to define cases of TD. Multivariate logistic regression was used to determine the predictors of TD. The independent variables in the regression model included patient characteristics (sex, age, insurance type, comorbidity, diagnosis, and number of prescribed drugs) and prescriber characteristics (type of medical institution and specialty).
resultsAmong 21 million patients, we identified 59,636,222 ambulatory care visits with NSAID/analgesic prescriptions; 13.3 % of these cases involved TD. The most frequent duplications were diclofenac/aceclofenac (12.4 % of TDs), diclofenac/talniflumate (11.2 %), and diclofenac/loxoprofen sodium (10.7 %). Male sex, older age, and a Charlson comorbidity index of ≥1 were associated with an increased likelihood of TD. Arthritis, injection administration (OR 3.676, 95 % CI 3.670–3.683), and the number of drugs per prescription were associated with an increased likelihood of TD. Orthopedic and pediatric specialties were associated with an increased likelihood of TD.
conclusionsThis study is the first to determine the prevalence of NSAID TD and the factors that were associated with its occurrence in South Korea. These results may help prevent TD and improve appropriate medication use.
