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
purposeTo evaluate the effects of zoledronic acid combined with simvastatin on postoperative functional recovery in elderly patients with osteoporotic intertrochanteric femoral fractures.
methodsThis retrospective study included 150 elderly patients with osteoporotic intertrochanteric femoral fractures who underwent proximal femoral nail antirotation (PFNA) fixation between May 2022 and May 2024. According to postoperative pharmacological regimens, patients were assigned to a conventional group (n = 79), receiving zoledronic acid alone, or a combination group (n = 71), receiving zoledronic acid plus oral simvastatin.Harris Hip Score (HHS), visual analogue scale(VAS)for pain, and serum bone metabolism markers, includingβ-C-terminal telopeptide of type I collagen (β-CTX), procollagen type I N-terminal propeptide (PINP), 25-hydroxyvitamin D[25(OH)D], and osteocalcin, were assessed preoperatively and at 3 and 6 months after surgery. The occurrence of internal fixation failure and refracture was also recorded. Statistical analyses were performed using R software.
resultsHHS scores increased progressively at postoperative assessment time points in both groups, whereas VAS scores showed a gradual decline. At 3 and 6 months after surgery, the combination group exhibited higher HHS scores than the conventional group (P < 0.05). 3 months after surgery, the VAS score in the combined group was lower than that in the conventional group (P < 0.05). With respect to bone metabolism, postoperative levels ofβ-CTX, PINP, and osteocalcin decreased over time in both groups, while 25 (OH) D levels increased.Differences in several bone metabolism indicators were observed between groups at postoperative time points. The proportions of internal fixation failure and refracture were lower in the combination group; however, the between-group differences were not statistically significant (P > 0.05).
conclusionIn elderly patients with osteoporotic intertrochanteric femoral fractures treated with PFNA, postoperative administration of zoledronic acid combined with simvastatin was associated with better hip function, favorable changes in bone metabolism and greater short-term improvement in postoperative pain compared with zoledronic acid alonebone metabolism.
