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
backgroundFractures of the metacarpal bones are common injuries of the hand that can be managed surgically with K-wire, intramedullary screws or plates. The study aimed to compare the radiological and functional outcomes of metacarpal shaft fractures treated with K-wire and plate fixation. METHODOLOGY: A prospective study comprising 100 patients with metacarpal shaft fractures was recruited in a nonrandomized manner and divided into two groups ( n = 50 per group) and followed up for 9 and 14 months. Participants in one group were fixed using K-wire, while fractures in the other group were fixed using plates. The outcome variables included time for union, functional outcomes (Disability of the Shoulder, Arm, and Hand scores), pain scores (Visual Analogue Scale [VAS]), metacarpophalangeal joint-range of motion (MCPJ-ROM) (using single-axis manual goniometry), and possible complications.
resultsThe median time of union was around 14 weeks in the plate group when compared to 17 weeks in the K-wire group ( P = 0.001). Overall functional outcomes were significantly better among participants in the plate group after 9 and 14 months, respectively ( P = 0.001). However, the median MCP joint active ROM (A-ROM) was found to be around 79.2° (88%) and 84.6° (94%) in the plating group and the K-wire group, respectively, at the end of 14 months. Median pain score was around 2 and 3 in the K-wire and the plating groups at the end of 9 months, respectively ( P = 0.001), but were the same at the end of 14 months. Median flexion MCPJ-AROM was better among participants fixed with K-wire both after 9 months (73.8° vs. 64.8°) and 14 months (84.6° vs. 79.2°), respectively. In terms of complications, there were 3 (6%) nonunion rates and 6 (3%) pin tract infections among the K-wire group, whereas there was only one case of nonunion among the plating group at the 14 th month ( P = 0.041).
conclusionsFixing metacarpal fractures using plates resulted in better overall functional outcomes with early union of fracture segments. However, pain scores were less in the K-wire group with better MCPJ-ROM among participants.
