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
introductionThe aim of this study was to examine Iranian adults aged 50 and above to determine the association between the prevalence of regional osteoporosis and their dietary intake of phosphorus, magnesium, potassium, and zinc. MATERIALS AND
methodsWe conducted a cross-sectional analysis of 1353 participants (406 with osteoporosis, 947 healthy) from the Iranian Multicenter Osteoporosis Study (IMOS-2021). A validated 168-item food frequency questionnaire was utilized to evaluate dietary intake. The lumbar spine, whole hip, and femoral neck were assessed for bone mineral density (BMD) with dual-energy x-ray absorptiometry. Multivariable logistic regression models were used to estimate odds ratios (ORs) for osteoporosis, adjusting for potential confounders.
resultsParticipants with osteoporosis were significantly older (63.76 vs. 59.61 years, P < 0.001), more likely to be women (67.2% vs. 50.4%, P < 0.001), and had lower intakes of all measured minerals (all P < 0.001). Correlation analyses revealed significant positive associations between all minerals and BMD at all skeletal sites (all P ≤ 0.01). In univariable models, insufficient phosphorus intake was associated with spine osteoporosis (OR = 1.56, P = 0.006) and total osteoporosis (OR = 1.49, P = 0.008), while insufficient potassium intake was linked to total osteoporosis (OR = 1.79, P = 0.031). After adjustment, only insufficient phosphorus intake remained significant for spine osteoporosis (OR = 1.71, P = 0.008).
conclusionOur findings suggest that dietary phosphorus may be independently associated with osteoporosis risk in this population; however, prospective studies incorporating objective dietary assessment, broader lifestyle factors, and fracture-related outcomes are needed to confirm causality and address residual confounding.
