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
This study aimed to compare the failure rates of two different sizes of plates and screws to stabilize critical-sized (7 mm) femoral defects in male Sprague‒Dawley rats (aged 10 weeks). Femoral defects were stabilized with either a 4-hole plate (length 29 mm, thickness 1 mm, 10 rats, Group 1) and 4 cortical screws (diameter 2 mm) or with a 6-hole plate (length 30 mm, thickness 0.6 mm, 9 rats, Group 2) and 4 cortical screws (diameter 1.5 mm). A polymethylmethacrylate spacer was inserted into the defects to reproduce the first stage of the induced membrane technique. Radiographic evaluations, macroscopic and histologic assessments of the induced membranes were conducted at 1 week and 4 weeks. No implant failure occurred in Group 1 whereas in Group 2, 4/9 (44.4%) implant failures occurred during the follow-up (p = 0.03). On histomorphometry, cell density was higher in Group 1 (4996 ± 716 cells / mm²) than in Group 2 (3500 ± 728 cells/mm²) (p = 0.0195) but the membrane thickness in Group 1 (735 ± 44 μm) was non-significantly lower than in Group 2 (979 ± 165 μm) (p = 0.4). This study suggests that, in rat models of critical-sized femoral defects (7 mm) to study the induced membrane technique, fixation plates with a thickness of 1 mm and four screws (2 mm in diameter) provide stable fixation without implant failure. In contrast, thinner plates (< 1 mm) combined with screws of smaller diameter (1.5 mm) result in a high rate of implant failure.
