what does this mean? b. Replicability Strengths for replication: The overall procedure is simple (review records, code FSDs, run tests). Subgrouping and statistical tests are clearly described. Barriers to replication: Operational definitions of FSD categories are not fully standardized. For example: what specific documentation counts as "sucking difficulty" or "food transition problem"? Without detailed coding rules, two reviewers could classify differently. No mention of inter-rater reliability checks or whether coders were blinded. The population came from one urban rehabilitation center, and referral patterns may differ elsewhere. Conclusion: Replication is possible in principle, but full reproducibility across sites would require clearer coding manuals and reliability metrics
