Treatment of Nonreplantable Total Thumb Amputation at the CMC Level Using Index Finger Pollicization.

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
backgroundPollicization of the index finger is a rarely performed reconstructive option for patients with total thumb amputations with nonsalvageable carpometacarpal (CMC) joint and thenar muscles. Successful pollicization can provide basic grasp and pinch to help patients carry out activities of daily living. We present a retrospective review of 4 patients who underwent index finger pollicization for traumatic total thumb amputations.
methodsA retrospective review of 4 cases of pollicization using an injured index finger for traumatic thumb amputation was performed. Patients available for follow-up were contacted for functional assessment. Outcomes including range of motion (ROM), grip strength, key pinch, 2-point discrimination, and Disabilities of the Arm, Shoulder, and Hand score were obtained. Functional thenar muscle and the CMC joint were absent in all cases. Injury mechanism was firework in 2 patients and crush in 2 patients.
resultsThe time from injury to pollicization ranged from 8 days to 17 months. Follow-up time ranged from 10 weeks to 3 years. Three patients regularly used the pollicized thumb in activities of daily living such as writing. Tip pinch and lateral pinch along with grip strength were weak in all cases; the best recorded pinch strength was 24% and grip strength was 25% compared with the contralateral hand. The ROM of the pollicized thumb was limited.
conclusionsIndex finger pollicization following total thumb amputation can be a viable last-resort option for patients. The pollicized digit acts as a sensate post and avoids further morbidity from the traumatized extremity.
