• What’s provided vs. what’s missing: None of the supplied items are actually ScienceDaily coral or coral-specific publication-bias / sampling-methods coverage. Only a general research-reporting guidance article is relevant to “methods/sampling” quality considerations.
• Known (general, evidence-based): SPIRIT-C 2026 (BMJ, Feb 25, 2026) extends SPIRIT 2025 with 17 essential reporting elements for pediatric RCT protocols—aiming to reduce under-specification that can later distort analyses (including how participants are sampled/measured and what analyses are planned).
