Effects of a 12-week combined exercise-nutrition intervention on body composition, physical fitness, and lifestyle disease indicators in women with normal weight obesity.

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
purposeThis study investigated the effects of 12 weeks of nutrition education and combined exercise training on body composition, physical fitness, and lifestyle disease indicators in women with normal weight obesity (NWO).
methodsTwenty-six women with NWO in their 30s (BMI 18.5-22.9 kg/m2, body fat ≥ 30%) were randomly assigned to either a diet education and exercise training group (DE+TR; n = 13) or a diet education only group (DE; n = 13). The DE+TR group performed 80 minutes of combined exercise (40 min aerobic + 40 min resistance) three days per week for 12 weeks with nutrition education. The DE group received nutrition education only. Body composition, physical fitness, and lifestyle disease indicators were measured pre- and post-intervention using two-way repeated measures ANOVA.
resultsBody fat mass and body fat percentage decreased significantly in both groups, while fat-free mass increased only in the DE+TR group (p < .05). Physical fitness parameters (grip strength, sit-ups, flexibility, standing long jump, VO2max) and all 1-RM tests improved significantly only in the DE+TR group. Lifestyle disease indicators improved significantly in the DE+TR group: hypertension markers (heart rate, systolic blood pressure, mean arterial pressure, rate pressure product), diabetes markers (fasting glucose, insulin, HOMA-IR), lipid profiles (total cholesterol, triglycerides, LDL-C, HDL-C), and atherosclerosis risk ratios all showed favorable changes (p < .05).
conclusionTwelve weeks of combined nutrition education and exercise training effectively improves body composition, physical fitness, and lifestyle disease indicators in women with NWO, providing more comprehensive health benefits than nutrition education alone. From a public health perspective, these findings support the implementation of combined exercise-nutrition programs in community health centers and workplace wellness programs for women identified with NWO.
