Cada grupo continha oito animais, mas os tend\u00f5es foram ent\u00e3o divididos entre an\u00e1lises biomec\u00e2nicas e histol\u00f3gicas. A amostra efetiva para cada fluxo anal\u00edtico foi, portanto, quatro por grupo. Esse detalhe \u00e9 essencial para julgar a precis\u00e3o dos resultados.<\/p>\n<h2>Os resultados biomec\u00e2nicos e histol\u00f3gicos n\u00e3o foram id\u00eanticos<\/h2>\n<p>Ambos os grupos de agente \u00fanico apresentaram valores de carga m\u00e1xima at\u00e9 a falha mais elevados do que o controle, mas a signific\u00e2ncia estat\u00edstica para esse endpoint foi relatada apenas para TB-500. Os achados histopatol\u00f3gicos variaram de acordo com o sistema de pontua\u00e7\u00e3o: TB-500 diferiu do controle para o escore total de Bonar, enquanto TB-500 e a combina\u00e7\u00e3o diferiram para o escore total de Movin. As an\u00e1lises de col\u00e1geno adicionaram um contexto mecanicista, mas n\u00e3o transformaram o experimento em um estudo de resultados cl\u00ednicos em humanos.<\/p>\n<h2>O resultado da combina\u00e7\u00e3o \u00e9 f\u00e1cil de distorcer<\/h2>\n<p>Os autores relataram que BPC-157 e TB-500 combinados n\u00e3o proporcionaram benef\u00edcio adicional em rela\u00e7\u00e3o aos agentes individuais.
