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
Purpose: To determine whether meniscal tear morphology independently predicts repair failure following arthroscopic meniscal repair after adjustment for patient-, meniscal- and repair-related characteristics and to quantify the incremental prognostic value of tear morphology beyond established clinical predictors. Methods: A retrospective multicenter cohort study included 500 consecutive patients undergoing primary arthroscopic meniscal repair with a minimum follow-up of 24 months. Repairable tear morphologies included longitudinal vertical, bucket-handle, radial, horizontal cleavage, complex, ramp and root tears. Patients undergoing revision meniscal repair, previous ipsilateral meniscal repair or transplantation, treatment of discoid meniscus, repair of degenerative root tears associated with advanced osteoarthritis, concomitant corrective osteotomy or arthroplasty or with insufficient operative or follow-up data were excluded. Meniscal characteristics included tear morphology, laterality, vascular zone and intraoperatively assessed tissue quality based on structural integrity, macroscopic degeneration and suture-holding capacity. Repair-related variables included repair technique (all-inside, inside-out or hybrid), number of fixation sutures, suture density and concomitant anterior cruciate ligament reconstruction. Repair failure was defined as subsequent ipsilateral meniscal reoperation. Kaplan-Meier analysis and multivariable Cox proportional hazards regression were used to evaluate repair survival and independent predictors of failure. Results: During a median follow-up of 45 months, 81 patients (16.2%) underwent reoperation. Five-year repair survivorship was 82.6%. Although repair survival differed among tear morphologies in univariable analysis (log-rank Conclusion: Meniscal tear morphology demonstrated limited independent prognostic value after adjustment for patient-, lesion- and procedure-related characteristics. Prognosis after arthroscopic meniscal repair appears to depend more strongly on the biological and mechanical context of the reparable meniscus than on tear configuration alone. Clinical decision-making should therefore move beyond descriptive tear classification toward comprehensive contextual assessment integrating tissue quality, vascularity, meniscal laterality and repair-related factors. Level of Evidence: Level III.
