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
backgroundTwo of the most prevalent techniques for tendon transfer are Pulvertaft weave (PTW) and side-to-side (STS) constructs. Our purpose was to compare pooled results from reported biomechanical properties of these approaches by a meta-analysis. Our null hypothesis was there are no significant differences in load to failure (LTF), initial construct stiffness, or cross-sectional area (CSA) between these techniques.
methodsWe performed a systematic review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to identify candidate studies. We included studies with direct LTF comparisons of PTW and STS constructs. We performed a meta-analysis of pooled data comparing the 2 techniques for initial construct LTF (N), stiffness (N/mm), and CSA (mm
resultsEight studies with a total of 235 tested human or porcine tendon reconstruction constructs (107 PTW, 128 STS) met our inclusion criteria. Eight studies reported initial construct LTF, with weighted mean values of 103 (±36) and 198 (±61) N for the PTW and STS groups, respectively (
conclusionsOur meta-analysis demonstrated significant increased initial construct LTF and stiffness with STS tendon coaptation as compared with PTW. We found no difference for initial CSA between the 2 techniques.
