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
purposePostoperative neutral limb alignment [femorotibial mechanical axis (FTMA) 180° ± 3°] is generally considered to be one of the prerequisites for successful total knee arthroplasty (TKA). However, the influence of residual malalignment on clinical and functional outcomes after TKA is unknown. Therefore, the purpose of this study was to investigate the relationship between postoperative limb alignment and clinical outcomes in Asian patients who underwent primary TKA.
methodsThe study included 220 knees with a mean age of 73.5 years who underwent primary TKA for varus-type osteoarthritis; the mean follow-up period was 3.6 years. Patients were divided into four groups based on postoperative FTMA: severe varus (FTMA < 174°, n = 15), mild varus (FTMA >177°and ≤174°, n = 61), neutral (FTMA 180° ± 3°, n = 128), and valgus (FTMA > 183°, n = 16). Knee Society Knee Score (KSKS) and Knee Society Functional Score (KSFS) were compared among the 4 groups.
resultsKSKS and KSFS showed significant improvement in all groups. There were no statistically significant differences for postoperative KSKS among the four groups. For KSFS, however, the severe varus and valgus groups exhibited significantly lower values compared with the mild varus and neutral groups.
conclusionPostoperative mild varus alignment as well as neutral mechanical alignment of the lower limb led to excellent functional outcomes. For the clinical relevance, postoperative mild varus alignment of the lower limb is acceptable following TKA for varus-type osteoarthritis. LEVEL OF EVIDENCE: IV.
