The Effect of Intra-articular versus Intravenous Injection of Mesenchymal Stem Cells on Experimentally-Induced Knee Joint Osteoarthritis.
Article in Journal of microscopy and ultrastructure. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers, 1 of them a synthesis that pooled it.
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
backgroundOsteoarthritis (OA) is a chronic degenerative debilitating disease, primarily affects joints, particularly weight-bearing areas. The surface layer of the articular cartilage breaks down and wears away leading to rubbing of bones, pain, swelling, and joint stiffness. AIM AND
objectivesThis study investigates the possible therapeutic effects of intra-articular versus intravenous injection of umbilical cord blood mesenchymal stem cells (UCB-MSCs) against mono-iodoacetate-induced OA of the knee joints in male albino rats, using histological and immunohistochemical techniques. MATERIALS AND
methodsThirty male adult albino rats were randomized into five groups as follows: Group (I) and (II): Served as control. Group (III): Osteoarthritic group. Group IV: Osteoarthritic and intraarticularly-injected MSCs. Group V: Osteoarthritic and intravenously-injected MSCs. Animals were sacrificed 1 month after stem cell injection, the right knee was prepared for histological techniques (Hematoxylin and Eosin and Toluidine blue stains) and immunohistochemical technique (Bax stain). Prussian blue stain was used to assess homing of MSCs in Groups IV and V.
resultsKnee joint surface was irregular, fissured, and fragmented in Group III. In Groups IV and V, affected area was filled with newly formed tissue. Toluidine blue showed a decrease in matrix staining in Group III compared to both control and MSCs-treated groups. Chondrocytes in Group III showed strong Bax immunoreactivity and this reaction decreased in Group IV and V; however, Group V immunoreactivity was more than Group IV. Prussian blue stain showed labeled UCB-MSCs in many chondrocytes in Group IV and few chondrocytes in Group V.
conclusionIntraarticularly-injected UCB-MSCs showed better healing of knee OA than intravenously-injected UCB-MSCs.
