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
Bone changes in patients undergoing pelvic radiotherapy remain unclear. This study initially utilized high-resolution peripheral quantitative computed tomography (HR-pQCT) to assess the dynamic changes in bone microarchitecture and volumetric bone mineral density (BMD) in patients with cervical cancer before and after concurrent chemoradiotherapy. This prospective, observational study included patients with squamous carcinoma of the cervix scheduled for concurrent chemoradiotherapy. Patients underwent HR-pQCT, dual-energy X-ray absorptiometry (DXA) and laboratory tests before chemoradiotherapy, and at three and six months post-chemoradiotherapy. DXA, serving as the clinical standard for measuring BMD, was employed alongside HR-pQCT to provide complementary insights into bone micro-changes. The primary endpoint comprised changes in total (Tt.vBMD), trabecular (Tb.vBMD) and cortical (Ct.vBMD) volumetric BMD at the distal radius and tibia between pre-chemoradiotherapy and 6 months post-chemoradiotherapy. A total of 21 patients were enrolled, and one patient chose to withdraw (median age: 54.5 years). Tt.vBMD significantly decreased three months (distal radius: -1.65%, P = 0.008; distal tibia: -2.4%, P < 0.001) and six months (distal radius: -3.03%, P = 0.003; distal tibia: -2.69%, P = 0.002) post-chemoradiotherapy compared to baseline. Similarly, Tb.vBMD and Ct.vBMD demonstrated a significant downward trend post-chemoradiotherapy, with mean percent changes at three months of -0.73% and - 1.59% for the distal radius, and - 1.95% and - 1.50% for the distal tibia, respectively. The trends in BMD changes measured by DXA align with those observed using HR-pQCT. Regarding the laboratory tests, estradiol levels significantly decreased post-chemoradiotherapy, while follicle stimulating hormone and luteinizing hormone levels significantly increased. The results found that concurrent chemoradiotherapy was associated with the changes in bone volume, microstructure and BMD, especially in BMD three months post-chemoradiotherapy. Most of the bone micro-changes had not reverted by six months. This study explored the feasibility of early fracture risk identification post-chemoradiotherapy, aiding physicians in taking timely measures to improve prognosis.
