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 evaluated the relationship between the valgus correction angle (VCA) and femoral parameters-neck-shaft angle (NSA), horizontal offset (HO), femoral length (FL), lateral distal femoral angle (LDFA), and hip-knee-ankle angle (HKA)-in Indian patients undergoing total knee arthroplasty (TKA). This study aims to assess the importance of individualized VCA adjustments, as opposed to fixed values, in optimizing surgical planning for the Indian population.
methodsA retrospective analysis was conducted on 400 patients (319 females, 81 males; mean age 65.14 years) undergoing TKA. Standardized preoperative scanograms were analyzed and parameters measured. Multiple linear regression was used to assess the relationship between VCA and femoral parameters.
resultsThe mean VCA was 6.5° ± 1.66°. LDFA had the strongest positive association with VCA (p < 0.001), followed by a significant negative correlation with HKA (p = 0.001) and FL (p = 0.004). NSA and HO showed no significant effect. The model was significant (F = 26.54, p < 0.05), explained 32.1% of the variance in VCA (adjusted R
conclusionsLDFA, HKA, and FL significantly influence VCA in Indian patients, underscoring the need for individualized preoperative VCA planning to enhance surgical accuracy in TKA. Taller patients and valgus knees require a lesser VCA than shorter patients with varus. The wide variation in VCA values supports the need for individualized preoperative planning rather than a one-size-fits-all approach.
