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

objective: To determine the presence of staphylococcal superantigen-specific IgE antibodies and degree of IgE-mediated sensitization, as well as whether or not those are associated with the severity of asthma in adult patients.

methods: This was a cross-sectional study involving outpatients with asthma under treatment at a tertiary care university hospital in the city of Rio de Janeiro, Brazil. Consecutive patients were divided into two groups according to the severity of asthma based on the Global Initiative for Asthma criteria: mild asthma (MA), comprising patients with mild intermittent or persistent asthma; and moderate or severe asthma (MSA). We determined the serum levels of staphylococcal toxin-specific IgE antibodies, comparing the results and performing a statistical analysis.

results: The study included 142 patients: 72 in the MA group (median age = 46 years; 59 females) and 70 in the MSA group (median age = 56 years; 60 females). In the sample as a whole, 62 patients (43.7%) presented positive results for staphylococcal toxin-specific IgE antibodies: staphylococcal enterotoxin A (SEA), in 29 (20.4%); SEB, in 35 (24.6%); SEC, in 33 (23.2%); and toxic shock syndrome toxin (TSST), in 45 (31.7%). The mean serum levels of IgE antibodies to SEA, SEB, SEC, and TSST were 0.96 U/L, 1.09 U/L, 1.21 U/L, and 1.18 U/L, respectively. There were no statistically significant differences between the two groups in terms of the qualitative or quantitative results.

conclusions: Serum IgE antibodies to SEA, SEB, SEC, and TSST were detected in 43.7% of the patients in our sample. However, neither the qualitative nor quantitative results showed a statistically significant association with the clinical severity of asthma. OBJETIVO:: Determinar a presença de anticorpos IgE específicos para superantígenos estafilocócicos e o grau de sensibilização mediada por esses, assim como se esses estão associados à gravidade da asma em pacientes adultos. MÉTODOS:: Estudo transversal incluindo asmáticos adultos em acompanhamento ambulatorial em um hospital universitário terciário no Rio de Janeiro (RJ). Os pacientes foram alocados consecutivamente em dois grupos de gravidade da asma segundo critérios da Global Initiative for Asthma: asma leve (AL), com asmáticos leves intermitentes ou persistentes, e asma moderada ou grave (AMG). Foram determinados os níveis séricos de anticorpos IgE antitoxinas estafilocócicas, e os resultados foram comparados por análise estatística. RESULTADOS:: Foram incluídos 142 pacientes no estudo: 72 no grupo AL (mediana de idade = 46 anos; 59 do sexo feminino) e 70 do grupo AMG (mediana de idade = 56 anos; 60 do sexo feminino). Na amostra geral, 62 pacientes (43,7%) apresentaram resultados positivos para dosagens de anticorpos IgE antitoxinas estafilocócicas: enterotoxina (TX) A, em 29 (20,4%); TXB, em 35 (24,6%); TXC, em 33 (23,2%); e toxic shock syndrome toxin (TSST), em 45 (31,7%). As médias das dosagens séricas de anticorpos IgE específicos anti-TXA, TXB, TXC e TSST foram, respectivamente, de 0,96 U/l, 1,09 U/l, 1,21 U/l, e 1,18 U/l. Não houve diferença estatisticamente significativa dos resultados qualitativos ou quantitativos entre os grupos. CONCLUSÕES:: A presença de anticorpos IgE séricos anti-TXA, TXB, TXC e TSST, foi detectada em 43,7% nessa amostra de pacientes, mas não houve associação estatisticamente significativa entre seus resultados qualitativos ou quantitativos e gravidade clínica da asma.
