The Association between a Recorded Diagnosis of Obesity and Clinically Significant Weight Loss in the Primary Care Setting: A Nationwide Registry.

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
introductionOverweight and obesity (OW/OB) are underdiagnosed. The primary aim was to assess whether a diagnosis of OW/OB recorded by a primary care physician (PCP) is associated with clinically significant weight loss, compared to a missed diagnosis. The secondary aim was to investigate the association between OW/OB diagnosis and patient attendance at dietary consultations.
methodsThis retrospective, observational cohort study was conducted using a nationwide healthcare database. The study included a random sample of 200,000 adults with BMI ≥25 kg/m2, recorded on a primary care visit, between 2014 and 2020. Patients with prior diagnosis of OW/OB or obesity-related complications were excluded. The independent variable was OW/OB diagnosis recorded by the PCP immediately after BMI measurement. The outcome variable was ≥5% weight loss at a second weight measurement within 9-15 months. Multivariate regression analysis was applied.
resultsOf the 200,000 people with OW/OB, 36,033 (18.0%) had a diagnosis of OW/OB, and 37,368 (18.7%) had a second body weight measurement, of which 7,635 (20.4%) lost ≥5% of their baseline body weight. The prescription rate of anti-obesity medication was 1.2% and did not differ between patients who achieved weight loss and those who did not. Those with a recorded diagnosis were 2.6 times more likely to visit a dietitian (odds ratio [OR] 2.57, 95% confidence interval [CI]: 2.56-2.64) and 2.5 times more likely to achieve weight loss (OR 2.53, 95% CI: 2.46-2.60). After adjusting for multiple confounders, including attendance at dietary consultation, people who received OW/OB diagnosis were 32% more likely to achieve weight loss (OR 1.32, 95% CI: 1.28-1.36, p < 0.001) compared to people with missed diagnosis.
conclusionsRecording a diagnosis of obesity among relatively healthy people is associated with clinically significant weight loss at 1-year follow-up, independent of attendance at dietary consultation. Early obesity diagnosis is a significant opportunity to promote weight loss in the primary care setting and may affect weight trajectory.
