Drug utilization evaluation of nonprescription H2-receptor antagonists and alginate-containing preparations for dyspepsia.
Article in British journal of clinical pharmacology, 2000. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
aimsTo evaluate the use, efficacy and adverse effects of nonprescription H2-receptor antagonists and alginate-containing preparations obtained from community pharmacies.
methodsQuestionnaires were distributed to customers from 39 pharmacies in Scotland and Wales.
resultsOf 767 customers recruited, 608 (79.3%) returned an initial questionnaire and 472 (61.5%) customers a second questionnaire. The vast majority of respondents (424, 69.7%) had suffered their symptoms on three or more occasions and 369 (60.7%) had previously tried medicines to relieve their symptoms. Referrals to a doctor were less frequent than recommended in guidelines and few of those who were referred actually saw a doctor. Over a quarter of those returning the second questionnaire claimed to be taking more than one product simultaneously for symptom control. Eight customers who were taking prescribed ulcer-healing drugs obtained H2-receptor antagonists. The majority of respondents (355/472, 75. 2%) obtained some or complete symptom relief using the product obtained and 369/472 (78.2%) were completely satisfied with their product. H2-receptor antagonists were more likely to produce complete relief of symptoms than alginate-containing preparations (P < 0.05). Only 14 respondents (3.0%) reported side-effects from the product used which were mostly gastro-intestinal.
conclusionsThe study demonstrated that drug utilization studies are feasible to carry out in a community pharmacy setting. While the results support published evidence of the efficacy and minimal toxicity of these products, they also highlight the possibility of H2-receptor antagonists being used outwith their licenced indications.
