Analogous comparison of registered brand name drugs of tablets and capsules commercially available in Thailand: A retrospective study.
Article in PloS one, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Drug name confusion or similar product packaging and labeling, also known as "look-alike, sound-alike" (LASA) medication error, is one of the most problematic causes of prescribing and dispensing errors. Therefore, this study aimed to compare the similarity of registered brand name drugs of tablets and capsules that are commercially available in Thailand to estimate the magnitude of LASA medication errors. Analogous comparisons of brand names using similarity in orthography (written forms with identical letters) were analyzed retrospectively. Tablets and capsules commercially available in Thailand and registered with the Bureau of Drug Administration, Food and Drug Administration (FDA) in 2012 as "dangerous drugs" and "specially controlled drugs" for humans and animals were included in this study. Descriptive statistics, including frequencies and percentages, were used in this study. The analogous comparison of brand name orthography was scrutinized, and the results revealed 1,668 brand names, which were categorized into three genres as follows: 1) Single brand names from a single manufacturer having the same active pharmaceutical ingredient (API) with numerous registration numbers (1,049 names, 62.89% of the total similarity results) 2) Single brand names from different manufacturers having the same API and possessing several registration numbers (615 names, 36.87% of the total similarity results) 3) Single brand names from different manufacturers with diverse APIs (four brand names, 0.24% of the total similarity results). Analogous results revealed that numerous identical brand names could be derived from the same manufacturers, APIs, dosage strengths, or otherwise. The results of this study recommend improvement on product registration to better ensure patient safety in the future.
