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

objectiveTo analyze the accuracy of deterministic and probabilistic record linkage to identify TB duplicate records, as well as the characteristics of discordant pairs.

methodsThe study analyzed all TB records from 2009 to 2011 in the state of Rio de Janeiro. A deterministic record linkage algorithm was developed using a set of 70 rules, based on the combination of fragments of the key variables with or without modification (Soundex or substring). Each rule was formed by three or more fragments. The probabilistic approach required a cutoff point for the score, above which the links would be automatically classified as belonging to the same individual. The cutoff point was obtained by linkage of the Notifiable Diseases Information System - Tuberculosis database with itself, subsequent manual review and ROC curves and precision-recall. Sensitivity and specificity for accurate analysis were calculated.

resultsAccuracy ranged from 87.2% to 95.2% for sensitivity and 99.8% to 99.9% for specificity for probabilistic and deterministic record linkage, respectively. The occurrence of missing values for the key variables and the low percentage of similarity measure for name and date of birth were mainly responsible for the failure to identify records of the same individual with the techniques used.

conclusionsThe two techniques showed a high level of correlation for pair classification. Although deterministic linkage identified more duplicate records than probabilistic linkage, the latter retrieved records not identified by the former. User need and experience should be considered when choosing the best technique to be used. OBJETIVO: Analisar a acurácia das técnicas determinística e probabilística para identificação de registros duplicados de tuberculose, assim como as características dos pares discordantes. MÉTODOS: Foram analisados todos os registros de tuberculose no período de 2009 a 2011 do estado do Rio de Janeiro. Foi desenvolvido algoritmo para relacionamento determinístico, usando conjunto de 70 regras, a partir da combinação de fragmentos das variáveis-chave com ou sem modificações (Soundex ou substring). Cada regra era formada por três ou mais fragmentos. Para a abordagem probabilística, foi necessário estabelecer ponto de corte para o escore, acima do qual os links seriam classificados automaticamente como pertencentes ao mesmo indivíduo. O ponto de corte foi obtido por meio do relacionamento da base de dados Sistema de Informação de Agravos de Notificação - Tuberculose com ela mesma, posterior revisão manual e curvas ROC e precision-recall. Foram calculadas a sensibilidade e especificidade para análise de acurácia. RESULTADOS: A acurácia variou de 87,2% a 95,2% para sensibilidade e 99,8% a 99,9% para especificidade para as técnicas probabilística e determinística, respectivamente. A presença de valores faltantes para as variáveis-chave e o baixo percentual da medida de similaridade para o nome e data de nascimento foram os principais responsáveis pela não identificação dos registros do mesmo indivíduo pelas técnicas utilizadas. CONCLUSÕES: As duas técnicas apresentam alta concordância para a classificação como par. Apesar de a técnica determinística ter identificado mais registros duplicados que a probabilística, a segunda recuperou registros não identificados pela primeira. A necessidade e a experiência do usuário devem ser consideradas para a escolha da técnica a ser utilizada.
