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
Background: Relative motion flexion orthoses (RMFOs) are a type of early mobilization based on the "quadriga effect." Currently, there are few published clinical outcome data and no documented treatment protocols. This study aimed to standardize our a rehabilitation protocol for early mobilization with relative motion for flexor tendon injuries within a 9-week program. Methods: A prospective study was conducted from April 2023 to June 2024, which included all patients who had undergone relative motion orthoses and rehabilitation for flexor digitorum profundus repair in zone I or II. The exclusion criteria were as follows: age younger than 18 years, more than 3 injured fingers, and lack of adherence, associated fracture, and surgical repair for more than 10 days. Final measurements at weeks 8 and 12 included total active motion; Strickland and Glogovac formula; Quick Disability of the Arm, Shoulder, and Hand questionnaire; grip strength (Jamar); and pain. Results: Ten patients underwent the RMFO protocol between April 2023 and June 2024, with at least 3 months of follow-up. Two patients were excluded from the study; the remaining patients (8) showed improvements in range of motion; Disabilities of the Arm, Shoulder, and Hand; Jamar; and visual analog scale scores. No complications such as proximal interphalangeal joint contracture, tenolysis, or rupture were reported. All patients returned to work by week 10. Conclusions: In this small prospective case report of RMFOs, we continue to increase the number of patients in the literature, and our results are compared with those of previous studies. In addition, we present our step-by-step approach to a 9-week program.
