Effect of behavioural modification for small portions size consumption on BMI in college students of North India: a quasi experimental study.

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
introductionLarge meal portions contribute to the rise in Body Mass Index (BMI) leading to higher burden of Non-Communicable Diseases (NCDs), especially among the youths. College students frequently exhibit poor dietary habits; thus, it is important to pay attention to their eating habits in order to lower their risk for NCD. Therefore, we conducted this study with objective to measure the effect of health promotion intervention for small portion size consumption behaviour on body mass index (BMI) among college students in Chandigarh, India.
methodsWe conducted this quasi-experimental research among college students aged 18-21 years from two colleges with co-education, having same streams considered as intervention and control from 2019 to 2020. Motivating group therapy, individual counselling, classroom training including power point presentations, lectures, and messaging via WhatsApp were implemented to the intervention group. No intervention was applied to the control group.
resultsOverall, the mean BMI decreased in the both the intervention (n = 149) and control groups (n = 142) between the baseline and 6 months post intervention follow up period. The difference in difference (DID) of mean using paired t-test analysis showed that the estimated difference between the two groups was statistically significant for BMI (0.21; 95% CI 0.117-0.244; p-value < 0.001) and for waist hip ratio (0.02; 95% CI 0.001-0.005; p-value 007). There was reduction of 8.1% (from 28.9 to 20.8%) in obese, while 2.7% (from 44.3 to 47.0%) increase in participants with normal BMI in intervention. On the contrary there was almost no change in the proportion of obese and overweight participants in control group after 6 months.
conclusionConsidering the higher surge of obesity especially among the Indian youths, this study provided significant contribution in the field of public health in view of effective health promotion intervention to reduce BMI levels, by which get hold of the rising trend of this alarming problem. We recommend pragmatic community level large scale randomised control trials with frequent and controlled follow up to generate further evidence.
