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 validate the effectiveness of the osteoporosis self-assessment tool for Asians (OSTA) in the screening and diagnosis of osteoporosis in men aged over 50 years and postmenopausal women in the northern Vietnam population. MATERIALS AND
methodsThis study included 8077 participants (7044 postmenopausal women and 1033 men aged over 50) who attended health examinations at the National Institute of Nutrition, Vietnam, from 2010-2019. Osteoporosis is defined by a T-score ≤ -2.5 at the femoral neck, total hip, or L1-L4. OSTA scores were assessed for identifying osteoporosis via receiver operating characteristic (ROC) curves. The optimal cut-off points, sensitivity, specificity, and areas under the ROC curves (AUCs) were determined.
resultsThe study showed that the prevalence of osteoporosis was 13.4% in men and 25.5% in women. In women, a higher BMI and OSTA scores decreased the OR of osteoporosis (all p-values < 0.001). In men, a higher BMI decreased the OR of osteoporosis (p-value < 0.001). The results showed that the OSTA value was -1 which had a sensitivity of over 70% in both men and women. The OSTA value was -4 which had a sensitivity of over 90% and specificity of over 80% in both men and women. The optimal OSTA value was -3 which had a sensitivity of over 90% and a specificity of over 80% in both men and women.
conclusionsThe OSTA might be a simple tool for the screening and diagnosis of osteoporosis in Vietnamese postmenopausal women and men aged over 50 years.
