Dark gray: Comparison, Light gray: Column compared with row, White: Row compared with column. Data are RRs (95% CI) in the column-defining treatment compared with the row-defining treatment or row-defining treatment compared with the column-defining treatment. For column compared with row, RRs higher than 1 favour the column-defining treatment. For row compared to column, RRs lower than 1 favour the row-defining treatment. RR = risk ratio. CI = confidence interval.
