Effect of Tendon Strip (FCR vs APL) on Outcome of CMC Thumb Joint Arthroplasty With Pyrocarbon Disk Interposition.

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
backgroundPyrocarbon disk interposition for carpometacarpal (CMC) thumb joint osteoarthritis can be performed with a flexor carpi radialis (FCR) or abductor pollicis longus (APL) tendon strip. With the FCR technique, a ligament reconstruction is performed in addition to disk fixation, whereas with the APL technique the disk is simply secured in place. Our aim is to compare long-term postoperative outcomes between both techniques.
methodsIn this observational study, we included 106 patients in 2 centers operated on between 2006 and 2011. We assigned patients to the FCR group or the APL group based on the respective tendon strip used. As a primary outcome, we analyzed postoperative key pinch. In addition, we analyzed postoperative tip pinch and tripod pinch, grip strength, range of motion, thumb height maintenance, and patient-reported outcome measures (PROMs).
resultsThe analysis showed clinically important stronger key pinch for the APL group (β = 1.28 kg). Tip pinch and grip strength showed higher outcome for the FCR group (β = 1.22 kg and 5.14 kg, respectively). Palmar abduction was in favor of the FCR group and opposition in favor of the APL group, but these were interpreted as not clinically relevant. Radiological thumb height maintenance and PROMs showed no clinical difference.
conclusionsPyrocarbon disk interposition arthroplasty for CMC thumb joint osteoarthritis can be secured with an APL or FCR tendon strip. At long-term follow-up, use of an APL tendon strip results in significantly higher key pinch and better opposition. Tip pinch, grip strength, and palmar abduction were better after use of the FCR tendon strip. The choice of the tendon strip can be based on outcomes considered most important for the individual patient.
