Difference means were used for continuous out-comes and their 95% CI was estimated; ORs were calculated for dichotomous data with their 95% CI, based on a random effects model for collective estimates.
Se tomó la media de las diferencias para los desenlaces continuos y se estimó su IC 95%, se calculó el OR para datos dicotómicos con su IC 95%, basado en un modelo de efectos aleatorios para las estimaciones colectivas.
