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
ObjectiveTo evaluate the preliminary effects of a screening-guided, individualized nutritional intervention combined with tailored resistance exercise on nutritional status, physical function, and frailty in hospitalized frail older adults and explore baseline factors associated with response magnitude.MethodsThis prospective, single-arm pilot before-and-after study enrolled 120 hospitalized frail older adults (mean age: 87.03 ± 5.65 years). Nutritional status was stratified using the Mini Nutritional Assessment-Short Form (MNA-SF). Patients at a risk of malnutrition or those with malnutrition (MNA-SF score ≤ 11) received individualized oral nutritional supplementation, whereas well-nourished patients (MNA-SF score ≥ 12) underwent weekly monitoring. Resistance exercise included standardized Theraband training, performed 3 times weekly for 20-30 min, with intensity individualized using the Borg Rating of Perceived Exertion. Outcomes were assessed at baseline and after 12 weeks. The minimal clinically important difference (MCID) for Short Physical Performance Battery (SPPB) was defined as an improvement of ≥1 point. Baseline factors associated with SPPB MCID achievement were analyzed using multivariate logistic regression.ResultsCompared with baseline, significant within-group changes were observed in serum transferrin, prealbumin, and albumin levels as well as MNA-SF scores (all
