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
Background: The necessity of lesser trochanter (LT) fixation during hemiarthroplasty for unstable intertrochanteric fractures in the elderly remains controversial. This study aimed to determine whether LT fixation influences functional recovery and clinical outcomes. Methods: We retrospectively analyzed 105 patients (aged ≥ 65 years) who underwent cementless hemiarthroplasty for unstable intertrochanteric fractures with displaced LT fragments. Patients were divided into Fixation (n = 33) and Non-fixation (n = 72) groups. The primary outcome was the Harris Hip Score (HHS) at 12 months. Secondary outcomes included operative time, blood loss, limb length discrepancy, hip flexor strength, and complications. Results: Mean Harris Hip Score (HHS) at 12 months did not significantly differ between the non-fixation and fixation groups (83.1 ± 12.1 vs 85.2 ± 6.9; mean difference, -2.1 points; p = 0.477). Incidence of hip flexor weakness was also similar (20.8% vs 9.1%; p = 0.171). Multivariate analysis showed that LT fixation was not an independent predictor of postoperative HHS (β = 2.53; 95% CI, -3.61 to 8.67; p = 0.413). However, the non-fixation group had significantly shorter operative times (124.7 ± 14.9 vs 134.0 ± 15.1 min; p = 0.004). Blood loss and complication rates were comparable between groups. Conclusion: In this retrospective cohort, routine anatomical fixation of a displaced LT during hemiarthroplasty was not associated with superior functional recovery in elderly patients with unstable intertrochanteric fractures. Omitting fixation shortened operative time without an observed increase in complications, suggesting that non-fixation may be a reasonable operative simplification in selected patients.
