Small Sample Size and Generalizability
Research gap analysis derived from 2 biology papers in our local library.
The gap
More research is needed to validate findings in larger, diverse populations for chronic sodium cyclamate administration (n=20), erector spinae plane block studies (16 cats), Gazania rigens leaf extract experiments (no specific number given), and NGAL determination in pediatric patients with asthma, sepsis, or kidney diseases.
Consensus across the literature
The papers collectively establish the need for larger sample sizes to improve generalizability but leave open how much this affects their respective fields.
Research trend
Emerging — attention growing, methods still coalescing.
Supporting evidence — 2 representative gaps
- Impact of Chronic Sodium Cyclamate Administration at a Daily Acceptable Dose on Carbohydrate Metabolism and Insulin Resistance (2026) · doi
The study was limited to a relatively small sample size (n=20 at baseline, n=18 at day 60) in experimental animals, which may affect generalizability of findings.
Keywords: limited relatively small sample size baseline experimental animals affect generalizability - Increased susceptibility to 4-HNE-induced toxicity and impaired development in a model of ALDH4A1-deficient pediatric epilepsy carrying the S352L variant (2026) · doi
Biological replicates vary between experiments due to the availability of animals for in vivo studies, which may affect consistency across different experimental conditions.
