Fig. 6From: Chitosan modifies glycemic levels in people with metabolic syndrome and related disorders: meta-analysis with trial sequential analysisTrial sequential analysis for the impact of chitosan supplementation on glycemic levels. a TSA on pooled result of glucose: The cumulative sample size was over the required information size (RIS) of 7242 and cumulative Z-curve crossed both the trial sequential monitoring boundary and conventional boundary. b TSA on pooled result of insulin: the cumulative Z-curve was crossed conventional boundary but not crossed the trial sequential monitoring boundary. c TSA on pooled result of HbA1c: the cumulative sample size was over the RIS of 2810 and cumulative Z-curve crossed both the trial sequential monitoring boundary and conventional boundaryBack to article page
