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
purposeThe SFAV (Simple Foot and Ankle Value) consists in asking patients how they rate their joint function on the day of the examination, as a percentage of that of a normal joint (0-100% scale with 100% being normal). The main objective was to validate the SFAV by determining its correlation with validated foot and ankle function scores.
methodsThis was a prospective study. 90 patients were included in three groups: patients 16 to 54 years old with an acute or subacute ankle pathology (foot/ankle trauma patient group), patients more than 55 years old with ankle or foot osteoarthritis (foot/ankle degeneration patient group), and adults of any age without foot or ankle pathology (control group). A self-administered questionnaire with the American Orthopedic Foot and Ankle Society, The European Foot and Ankle Society, the Foot and Ankle Outcome Score, the Visual Analogic Scale, and the SFAV was given at three different timepoints (enrollment, preoperative visit, and 6-month postoperative visit) to the patients. The validity of the SFAV was investigated by determining its correlation with the existing foot and ankle PROMs using Spearman's correlation; test-retest reliability, the responsiveness to change, and the discriminative ability of the SFAV were also analyzed. The significance threshold was set at 0.05.
resultsThe SFAV was significantly correlated with the AOFAS, EFAS, and FAOS at all tested time points, with all p values below 0.033. SFAV scoring was reliable over time, as p values resulting from the comparison between initial and preoperative SFAV were all above the significance threshold. SFAV scoring was responsive to change, based on the comparison between pre- and postoperative SFAV (p < 0.05). Like for the AOFAS, EFAS, and FAOS, SFAV provides good discrimination between a healthy subject and a patient. The control group scores and initial consultation scores of the pooled patient's groups were statistically correlated (p < 0.05).
conclusionThe SFAV is a valid outcome measure correlated with the AOFAS, EFAS, FAOS, and VAS. LEVEL OF EVIDENCE: Level of evidence III.
