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: Posterolateral impaction fractures of the tibial plateau are known to be associated with anterior cruciate ligament (ACL) tears. These fractures are often related to high energy pivoting injuries, which is why the frequency of such injuries is of key concern for patients undergoing primary ACL reconstruction. The objective of this study is to evaluate the occurrence of posterolateral tibial fractures, as well as concomitant injuries in patients undergoing primary ACL reconstruction. Methods: A retrospective case series was conducted to study the occurrence and type of posterolateral tibial impaction fractures in patients undergoing ACL reconstruction between October 2015 and October 2020. Patients records were reviewed to collect patient demographics, exact injury patterns and details about concomitant injuries. Descriptive statistics were performed to determine the incidence of each type of posterolateral tibial plateau impaction fracture, as well as concomitant injuries. Results: Of the 556 knees with primary ACL reconstruction, a total of 171 posterolateral tibial plateau impaction fractures were identified. 385 patients showed no fracture. Intraoperative arthroscopic examination showed lateral meniscus (LM) tears in 144 cases and medial meniscus (MM) tears in 163 cases. LM posterior root tears were found in 21 patients, MM posterior root tears in eight patients. Medial meniscal ramp lesions were found in a total of 39 knees. Conclusion: 30.8% of the patients showed posterolateral tibial plateau impression fractures, here LM tears were more frequent with the highest incidence in IIIB fractures. MM tears are more frequent in patients without posterolateral impaction fractures, while LM posterior root tears are more frequent than MM posterior root tears among the whole study population. The clinical relevance of this study lies in the exact analysis of posterolateral tibial plateau fractures in patients with ACL lesions, with the resulting therapeutic consequences dependent on the fracture type and concomitant injuries.
