1 · What the graph read from it

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.

2 · The registry

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] This study aimed to investigate the effects of a preoperative exercise intervention program on physical function in patients with knee osteoarthritis (KOA) scheduled for total knee arthroplasty (TKA). [Participants and Methods] Twenty-four patients with KOA scheduled for TKA participated in a preoperative exercise program focusing on non-operated limbs. Physical function was evaluated pre- and post-intervention, including knee extension strength (KES), hip abduction strength (HAS), knee range of motion (ROM), pain during activity and at rest (NRS), and performance measures (CS-30, 40 mFWT). Changes were analyzed for statistical significance, and 95% confidence intervals were compared with previously reported MDC95 values. [Results] Activity-related pain, KES, HAS, knee ROM, and CS-30, and 40 mFWT showed statistically significant changes post-intervention. Changes in activity-related NRS and CS-30 levels exceeded the MDC95. [Conclusion] Knee joint function and physical performance of patients with KOA scheduled for TKA significantly changed after eight weeks of preoperative exercise program. Changes exceeding the MDC95 in activity-related pain and CS-30 suggest that our exercise program may have enhanced preoperative physical function.
