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
Purpose: Individuals with excessive knee rotation have higher levels of dysfunction and disability. An inexpensive, and reliable method to assess knee internal (IR) and external (ER) rotation will improve the assessment of knee injuries. The study explored the reliability and measurement error of two methods of knee rotation measurement. The study tested the hypothesis that the digital inclinometer will provide reliable measures of knee internal and external rotation and that the digital inclinometer measurements will be consistent with the measurements made with the electromagnetic tracking system. Methods: Twenty (20) participants without knee injury participated. Knee IR and ER were measured using electromagnetic tracking and a digital inclinometer. The intraclass correlation coefficient (ICC Results: The within device ICC values ranged from 0.826 to 0.939 for both devices. The within-device minimal detectable change (MDC) ranged from 1.2° to 1.9°. The ICC values for EI and IR measures collapsed between the devices, ranged from 0.717 to 0.859. The MDC calculated between devices ranged from 1.6° to 1.9°. Conclusion: The results of the current study show that knee IR and ER can be measured reliably with both measurement techniques. The measurement of knee ER and IR did not differ between the two devices or between the right and left sides. Level of Evidence: Level IV, diagnostic, case series study.
