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
introductionTrapeziectomy and ligament reconstruction tendon interposition (LRTI) is a commonly used procedure in the management of first carpometacarpal osteoarthritis. Debate persists regarding the degree of biomechanical improvement following trapeziectomy and subsequently LRTI. This preliminary, single-centre, in vivo, biomechanical study addresses the biomechanical effect of LRTI following trapeziectomy at the time of surgery, with each participant acting as their own control.
methodsTrapeziectomy and LRTI were performed under wide-awake local anaesthetic with no tourniquet (WALANT) with a flexor carpi radialis (FCR) donor graft. Key pinch grip was assessed in each participant.
resultsThe surgical method that resulted in biomechanically the most significant decrease in grip strength compared with preoperative grip strength was trapeziectomy alone with a mean difference of 4.27kg, which was also statistically significant (Tukey's test
conclusionsOur preliminary research presents a novel method to evaluate for biomechanical advantages following trapeziectomy and LRTI. This supports the biomechanical advantages of FCR LRTI following trapeziectomy, at the time of surgery. There is scope for this research process to be applied more widely in future.
