I'm currently writing a critique on an RCT and my essay should include a report on the findings of the study. I have very minimal knowledge on interpreting statistics and papers.
I'm confused on how to interpret the confidence intervals for these results. I do know that the two-tailed p-value (set at <0.05) is statistically significant, but I'd appreciate any help and explanation about CIs.
"A significant interaction effect was observed for total fatigue (F = 7.63;P = .001). Post‐hoc ANCOVAs indicated that, after the intervention, the telerehabilitation group improved total fatigue perception significantly (P < .001) compared with the control group. This improvement was maintained after the 6‐month follow‐up period (P = .002) (Fig. 4). The ES was large after the intervention (d = −0.89; 95% CI, −1.30, −0.48) and was moderate after follow‐up (d = −0.74; 95% CI, −1.19, −0.29)."
