Hypochlorhydria and achlorhydria are associated with false-positive secretin stimulation testing for Zollinger-Ellison syndrome.
Article in Pancreas, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesSecretin stimulation testing (SST) is used to evaluate patients with hypergastrinemia in the diagnosis of Zollinger-Ellison syndrome. Case series have documented false-positive SST in patients with achlorhydria. This study reviews our experience with SST in hypochlorhydric and achlorhydric patients.
methodsWe examined 27 patients with hypochlorhydria or achlorhydria based on a predefined basal acid output (BAO) measurement of less than 5.0 mEq/h who also underwent SST for diagnosis of Zollinger-Ellison syndrome. We report the frequency of false-positive SST results in this setting.
resultsThree hundred thirty patients underwent gastric analysis of which 27 had BAO of less than 5.0 mEq/h and SST conducted. The mean (SD) fasting gastrin level was 247 (304) pg/mL, and the mean (SD) BAO measurement was 1.6 (1.8) mEq/h. Twenty patients were off, and 7 were on antisecretory therapy at time of testing. Four patients had false-positive SST results: 3 with gastric atrophy (BAO = 0 mEq/h) and 1 with drug-induced hypochlorhydria (BAO = 0.5 mEq/hr). These false-positive test results were confirmed by structural and functional imaging studies.
conclusionsWe have identified a 14.8% false-positive rate in SST in patients with hypochlorhydria or achlorhydria. Growing literature has identified severe consequences associated with discontinuing antisecretory treatment for testing; therefore, SST will require interpretation in the setting of gastric acid suppression and needs to be interpreted in this context.
