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
backgroundThe 21-item Fall Risk Index questionnaire (FRI-21) was developed to screen for fall risk in older adults. It showed great potential in assessing the fall risk in stroke population. However, no previous study investigated its reliability and validity in people with stroke in Hong Kong.
aimThis study aimed to translate FRI-21 to Chinese and investigate: 1) the FRI-21 scores between people with stroke and healthy older adults; 2) the test-retest reliability of the FRI-21 in people with stroke; 3) the convergent validity by correlated of the FRI-21 with Berg Balance Scale (BBS); 4) the predictive ability of FRI-21 on the fall occurrence in the 2 years follow-up; 5) the optimal FRI-21 cut-off score that distinguishes faller and non-faller among people with stroke in the 2 years follow-up; and 6) the ceiling and floor effects of the Chinese version of the FRI-21.
designCross-sectional study.
settingUniversity-based rehabilitation laboratory. POPULATION: In total, 57 people with stroke and 31 healthy older adults.
methodsThe FRI-21 test was assessed in people with stroke on Day1 and Day 2 (7 days after Day 1), and assessed in healthy older adults on Day 1 only. The BBS was also assessed in Day 1.
resultsThe mean FRI-21 scores in subjects with stroke was 7.37. The FRI-21 demonstrated good inter-rater reliability (intraclass correlation [ICC] 0.74) and good test-retest reliability (ICC=0.798) in people with stroke. The FRI-21 scores demonstrated significant negative correlations with the BBS (r=-0.308). The FRI-21 score was found to be a significant predictor (OR 1.40 [95% CI 1.06-1.85], P=0.018) of fall in the 2 years of follow-up. The receiver operating characteristic curve analysis identified an optimal FRI-21 cutoff score of 7.5, showing an acceptable diagnostic power in distinguishing faller and non-faller among people with stroke (area under curve = 0.723, P=0.002), with moderate sensitivity (80.0%) and specificity (60.5%). Ceiling and floor effects are negligible.
conclusionsThis study reflects the reliability and validity of the FRI-21 as self-administered tool for assessing fall risk in individuals aged 50 and over with stroke, and without cognitive impairments. A cut-off score of 7.5 was identified to distinguish faller and non-faller in people with stroke. The FRI-21 score was a significant predictor of fall in people with stroke. It effectively differentiates fall risk between people with stroke and healthy older adults. Future research should increase the sample size to enhance the generalizability of the findings. CLINICAL REHABILITATION IMPACT: Clinicians can use this tool to efficiently identify high-risk individuals among stroke survivors and implement targeted early interventions. This early fall risk screening tool allows healthcare providers to initiate preventive measures and intensive rehabilitation protocols for those at greatest risk, potentially reducing secondary complications, improving functional outcomes, and decreasing hospital readmission rates.
