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
purposeTo compare infra-tubercle (IKO) versus retro-tubercle (RKO) slope-reducing osteotomy performed with revision anterior cruciate ligament reconstruction (ACLR) on survivorship, anterior laxity, alignment, union, complications and patient-reported outcome measures (PROMs).
methodsRetrospective comparative cohort at a tertiary centre including 107 consecutive revision ACLR + slope-reducing osteotomy cases (IKO n = 50; RKO n = 57). Primary outcomes were Kaplan-Meier survivorship for (1) revision-only and (2) global failure (earliest of revision or instrumented anterior laxity > 5 mm). Secondary outcomes included Rolimeter side-to-side laxity at 2 months/1 year/2 years, radiographic posterior tibial slope (ΔPTS) and hip-knee-ankle angle (ΔHKA), union time, complications/reoperations and knee injury and osteoarthritis outcome score (KOOS). Between-group comparisons used t-tests/χ²; survival was compared by the log-rank test. Significance p < 0.05.
resultsAt mean follow-up of 27.9 ± 4.4 months, crude revision rates were 5.26% (3/57; 95% confidence [CI]: 1.8%-14.4%) for IKO versus 20.0% (10/50; 95% CI: 11.2%-33.0%) for RKO (p = 0.048). Five-year Kaplan-Meier survivorship estimates showed no statistically significant differences at all endpoints. IKO demonstrated significantly lower instrumented laxity at all time points: 2.4 ± 2.1 versus 3.3 ± 2.0 mm at 2 months (p = 0.034), 3.5 ± 2.3 versus 4.8 ± 2.7 mm at 1 year (p = 0.010), and 4.0 ± 2.9 versus 5.8 ± 4.2 mm at 2 years (p = 0.013). Coronal alignment changes differed significantly between groups (ΔHKA + 0.45° ± 0.58° for IKO vs. -1.32° ± 1.20° for RKO, p < 0.001). PTS reduction was comparable between groups (ΔPTS -8.20° ± 1.61°, 95% CI: -8.6 to -7.8 vs. -7.90° ± 1.74°, 95% CI: -8.4 to -7.4, p = 0.35). Hardware removal was more frequent following IKO (38.8% vs. 17.2%, p = 0.016). Union was achieved universally in both groups, though healing time was longer after IKO (4.0 ± 0.9 vs. 3.2 ± 0.6 months, p < 0.0001).
conclusionIn revision ACLR for elevated PTS, IKO and RKO yield comparable survivorship and PROM gains. IKO demonstrated better preservation of coronal-plane alignment and lower residual anterior laxity, at the trade-off of more frequent elective hardware removal and slightly longer time to union. These data can inform technique selection and counselling. LEVEL OF EVIDENCE: Level III, retrospective comparative cohort.
