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
backgroundThis study compared postoperative hip muscle strength, as well as clinical outcomes, between elderly patients with femoral neck and intertrochanteric fractures.
methodsWe conducted a retrospective cohort study at a Level-1 trauma center involving patients aged ≥ 60 years who underwent hip internal fixation or hip replacement for femoral neck or intertrochanteric fractures. Postoperative hip flexion and abduction strength, with strength deficits calculated by subtracting the strength of the injured side from the normal side, were collected. The Harris Hip Score (HHS), Barthel Index (BI), de Morton Mobility Index (DEMMI), Functional Reach Test (FRT), 5-time Sit-to-Stand Test (5TSTS), and Timed Up and Go Test (TUG) were also recorded. All outcomes were analyzed at 3 months follow-up or later.
resultsThe 135 eligible patients were analyzed. The femoral neck group (n = 65) had greater hip flexion strength on the injured side compared to the intertrochanteric group (n = 70) (6.27 kg vs. 5.47 kg, p = 0.026). The femoral neck group had less hip flexion strength deficits (0.59 kg, 8.96%) compared to the intertrochanteric group (1.30 kg, 17.04%) (p < 0.05). Hip abduction strength on the injured side and the strength deficit were comparable between groups. Clinical outcomes (HHS, DEMMI, FRT, 5TSTS, TUG) also favored femoral neck group (p < 0.05), while BI scores were comparable. After adjusting for age, only the difference in hip flexion strength deficit remained significant (adjusted p = 0.039).
conclusionFemoral neck fractures showed better hip flexion strength, even after age adjustment. However, functional and performance outcomes became comparable after controlling for age. Intertrochanteric fractures may benefit from focused rehabilitation on flexor strengthening, balance training, and prolonged gait aid use to reduce fall risk.
