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: Evaluating knee joint function, activity level, and osteoarthritis severity in patients at least 8 years after post-operative knee septic arthritis (SA) following anterior cruciate ligament reconstruction (ACLR). Methods: From May 2010 to January 2012, 39 patients at our institution were treated for knee SA following ACLR using graft-retaining treatment protocols. Follow-up examinations after a minimum of 8 years included clinical examination, measurement of anterior tibial translation (rolimeter), International Knee Documentation Committee Subjective Knee Form (IKDC), 12-Item Short Form Health Survey (SF-12), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and Marx and Tegner scores. Osteoarthritis severity was described on radiographs using the Kellgren-Lawrence scale. Synovial fluid was aspirated from patients with persistent infection signs and evaluated using multiplex polymerase chain reaction (PCR). Based on ACLR graft, sex and preoperative Tegner score (±1), a 1:1 propensity score matched control group including patients with ACLR without knee SA signs was assembled. Results: Matching resulted in 17 patients per group. While the patient-reported outcome measures (PROMs) (IKDC, Tegner, Marx and SF-12) showed no significant differences between the groups ( Conclusions: SA after ACLR, when treated with a standardized graft-retaining protocol, results in higher OA severity, worse WOMAC scores and persistent range of motion limitations at long-term follow-up, while other PROMs and activity level remained comparable to those of non-infected cases. Level of Evidence: Level III.
