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
introductionThe occurrence of associated both-column acetabular fractures (ABC-AFs) is common in the elderly, yet their morphological characteristics compared to younger adults remain unclear. MATERIALS AND
methodsThis retrospective study analyzed 123 cases of ABC-AFs: elderly patients (≥ 65 years, n = 47, group A) and younger adults (< 65 years, n = 76, group B). Using Mimics and 3-matic, fracture line (FL) distributions in the anterior column (AC), quadrilateral plate (QP), and posterior wall (PW) fragments were examined. Comparisons focused on the articular surface, ilium, QP area, and retro-acetabular surface (RAS). Harris hip scores (HHS) were recorded and compared one-year post-surgery.
resultsThe distribution of FLs of the AC fragment on the anteroinferior wall, acetabulum, inner and outer sides of the ilium was similar between groups A and B except that group A had sparser FL distribution on the posterosuperior rim and fewer FLs extending into the sacroiliac joint. A comparable pattern of FLs of the QP fragments on the QP area and the RAS was also confirmed. On the RAS, group A exhibited fewer cranial transverse lines (8.5% vs. 25.0%) and more inverse lines (44.7% vs. 23.7%) than group B (p = 0.011). A higher incidence of PW fragments was identified in group A (72.3% vs. 53.9%, p = 0.042). The number of intra-articular fragments was higher in group A than group B (3.8 vs. 3.4, p = 0.031), but the composition of the articular surface was similar. The average HHS was 77.6 in group A and 83.0 in group B (p = 0.007), with excellent/good ratios of 59.5% and 74.7% (p < 0.001), respectively.
conclusionsThe similar morphological patterns of ABC-AFs and favorable functional outcomes suggest that surgical principles for younger patients could be applicable to elderly patients, with careful considerations for osteoporosis and co-morbidities.
