A Study on Prevalence of Phenyl Thiocarbamide (PTC) Taste Blindness Among Obese Individuals.
Article in Journal of clinical and diagnostic research : JCDR, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
introductionTaste blindness to the phenylthiocarbamide (PTC) is an inherited trait that is shown to influence our food and dietary preferences which in turn influence our body weight. Obesity is a global epidemic issue known to be on rise among the developing countries. Relating taste perception to obesity, the present study was undertaken to assess the prevalence of phenylthiocarbamide (PTC) taste blindness among obese individuals. MATERIALS AND
methodsThree hundred and fifty individuals of age group 20-40 y were recruited from the local community for the present cross sectional study. Anthropometric measurements were taken and BMI was calculated. Subjects were classified as underweight, normal, overweight and obese based on their BMI. Normal, overweight and obese individuals were then asked to taste the commercially available PTC test papers and classified as non tasters and tasters of PTC.
resultsOut of 350 individuals, mean age group of 30±6.02 y, based on their BMI they were divided into 4 groups, Group A-underweight (16%), Group B-normal (35%), Group C-overweight (28%) and Group D-obese (21%) individuals. In group B, 28% were non tasters of PTC and 65% were tasters. In group C, 82% were non tasters and 13% were tasters and in Group D, 81% were non tasters and 19% were tasters of PTC. The PTC non taster phenotype individuals showed higher BMI as compared with the tasters' phenotype.
conclusionExploring the novel connections between taste perception and obesity would help us to gain a control over the global epidemic-Obesity, which is the crux factor for various other health problems. The study advocates the usage of PTC tasting as a reliable indicator of weight gain susceptibility.
