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
objectiveTo investigate the short- and medium-term effectiveness of percutaneous compression plate (PCCP) internal fixation for femoral neck fractures in the elderly.
methodsThe clinical data of 32 elderly patients with femoral neck fracture treated with PCCP internal fixation between January 2012 and January 2019 were retrospectively analyzed. All of them were traumatic fractures. The causes of injury were falling in 20 cases, traffic accident in 7 cases, and falling from height in 5 cases. According to Garden classification, there were 7 cases of type Ⅱ, 15 cases of type Ⅲ, and 10 cases of type Ⅳ; there were 12 cases with Singh index level Ⅳ, 14 cases with level Ⅴ, and 6 cases with level Ⅵ; the bone mineral density of femoral neck was 0.610-0.860 g/cm
resultsThe operation time was 35-135 minutes (mean, 73.4 minutes), the intraoperative blood loss was 75-385 mL (mean, 116.4 mL), the hospitalization stay was 3-15 days (mean, 8.3 days). At 1 week after operation, the Garden alignment index of fracture reduction was grade Ⅰ in 25 cases, grade Ⅱ in 6 cases, and grade Ⅲ in 1 case. One case of superficial infection of the incision occurred after operation, and no early complications such as deep vein thrombosis in the lower extremities, pulmonary embolism, or bedsores occurred. All the patients were followed up 2.1-4.0 years, with an average of 2.7 years. Except for 2 cases of delayed union (displaced trans-neck and subhead fractures), no nonunion of fracture and failure of internal fixation occurred, the fracture healing time was 4-8 months, with an average of 4.9 months. Femoral neck shortening occurred in 12 cases (37.5%); osteonecrosis of the femoral head occurred in 3 cases (9.4%), all of which were displaced trans-neck and subhead fractures, of which 2 cases received total hip arthroplasty and the other received conservative treatment. The Harris scores of the hip joint at 3 months, 2 years after operation and at last follow-up were significantly improved when compared with those before operation (
conclusionFor elderly patients with femoral neck fractures without severe osteoporosis and with relatively good physical conditions, PCCP internal fixation can achieve satisfactory short- and medium-term effectiveness, but there is a certain risk of osteonecrosis of the femoral head.
