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
purposeFinding prognostic factors for a subsequent injury after an anterior cruciate ligament (ACL) reconstruction.
methodsWe re-analysed the data of two intervention studies on adults with a hamstrings or quadriceps tendon ACL reconstruction. All participants were prospectively monitored for 24 months. At the end of the individual postsurgery rehabilitation, numerous self-reported and objective functional outcomes were quantified, all potential secondary injuries (primary outcome was the occurrence of secondary ipsi- or contralateral ACL injuries) and all rehabilitation and training measures were prospectively monitored. The association of potential factors with a secondary injury risk was determined using logistic mixed models.
resultsWe included 148 participants (mean age 25.3 years [standard deviation 5.1 years], 63 females). Eight participants had a subsequent ACL injury, among them seven ispilateral and one contralateral side ACL rupture. The final model for the likelihood of a subsequent ACL injury led to a sensitivity (correctly classified participants who had a subsequent ACL injury) of 83.3% and to a specificity (correctly identified participants without who did not have a subsequent ACL injury) of 100% (n = 93). The main contributing factors to subsequent ACL or any subsequent other injuries were: higher kinesiophobia values (odds ratio [OR] = 2.0, 95% confidence interval [CI] = 1.1-3.4), higher knee loading levels during activity (Tegner activity scale, OR = 29, 95% CI: 1.1-791), lower performance levels at the Balance front hop (OR = 0.13, 95% CI: 0.03-0.52), and higher dynamic valgus (knee separation distance in the frontal plane) during the landing of a drop jump landing (OR = 0.80, 95% CI: 0.65-0.98).
conclusionMost of the predictive factors for a second subsequent injury after an ACL reconstruction are modifiable by adequate training and rehabilitation measures. The modification of these factors might decrease the secondary risk of injury risk. LEVEL OF EVIDENCE: Level II, a prospective cohort study.
