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
purposeThis study compared total knee arthroplasty (TKA) outcomes between cementless and hybrid fixation, with separate analysis of tibial and femoral cementation. The primary hypothesis was that equivalence would exist in implant survivorship between cementless and hybrid fixation techniques. The secondary hypothesis was that cementless and hybrid TKAs would demonstrate comparable mid-term surgery-free survival rates, rates of aseptic reoperation and functional outcomes.
methodsA multicentre retrospective study was conducted using prospectively collected data from a large cohort, all implanted with the same deep-dish mobile bearing. Patients were divided according to the fixation method: fully cementless, femoral cemented/tibial uncemented and tibial cemented/femoral uncemented. The survival rates of cementless and hybrid TKA were compared with a median follow-up of 27 months. Evolution of functional outcomes (International Knee Society [IKS] score, range of motion [ROM]) from preoperative to 5-year follow-up were also compared. Propensity score matching (PSM) was performed to balance covariates (age, sex, body mass index and patellar procedure) between groups.
resultsAmong the 5361 primary TKA included (4549 cementless, 435 tibial hybrid and 377 femoral hybrid), 1505 reached the 5-year follow-up. Five-year revision-free survival rate was 98.7% (95% confidence interval: 98.2; 99.1) for cementless, 97.8% (94.6; 99.1) for tibial hybrid (p = 0.537) and 98.4% (94.9; 99.5) for femoral hybrid (p = 0.669). Cumulative surgery-free survival rates and functional outcomes at 5 years showed no significant differences between groups with clinically comparable results.
conclusionNo difference in survivorship was observed between cementless and hybrid TKA at 5 years in this cohort of 5361 patients, whether the tibia or femur was cemented. Rates of reoperation and aseptic reoperation were also comparable, as were clinical outcomes. These results suggest that the choice between hybrid and cementless fixation does not impact mid-term TKA survival. LEVEL OF EVIDENCE: Level III.
