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
backgroundProgressive collapsing foot deformity (PCFD) represents a multifaceted three-dimensional condition. However, there has been limited discussion regarding how the morphology of each bone affects PCFD. PURPOSE: To determine morphological differences within each bone of the foot and ankle in females affected by PCFD compared to asymptomatic controls. STUDY
designComparative cross-sectional study.
methodsWe hypothesized the medial column bones would exhibit the most substantial shape differences between groups. We developed multiple statistical shape models (SSMs) to analyze the 3D shape of the distal tibia, distal fibula, talus, calcaneus, navicular, cuboid, cuneiforms, and metatarsals. We quantified and compared results between 23 female PCFD patients and 23 asymptomatic females.
resultsSSM analyses revealed significant modes of variation across several bones. Notably, the fibula showed reduced fibular tip height in PCFD patients. The talus exhibited decreased lateral and posterior processes and an inferior, adducted talar head shift. The calcaneus had a narrowed posterior facet and anteriorly shifted anterior-medial facet. In PCFD patients, the navicular tuberosity was displaced toward the body with medial-inferior articular defects. The cuboid showed increased prominence of the tuberosity and beak.
conclusionThese SSM results provide novel characterization of the 3D shape of bones from tibia to metatarsals in PCFD and asymptomatic females. Patients with PCFD exhibited distinct 3D shape differences in the distal fibula, talus, calcaneus, navicular, and cuboid, suggesting that PCFD is primarily characterized by deformities of the hindfoot bones.
