1 · What the graph read from 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.

2 · The registry

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

introductionOsgood-Schlatter disease (OSD) is a common cause of anterior knee pain in adolescent athletes due to repetitive stress on the tibial tubercle. The posterior tibial slope angle (PTSA) and the Insall-Salvati Index (ISI) play a role in knee biomechanics. However, to our knowledge, the posterior tibial slope and patellar height have not been compared in operated versus nonoperative OSD patients. The purpose of the current study is to compare the differences in the PTSA and the ISI between operative and nonoperative patients with OSD. MATERIALS AND

methodsThe study was approved by the College of Medicine's Institutional Review Board. A retrospective review was performed on 75 adolescent athletes with OSD between 2008 and 2019. The data extracted included: age, sex, body mass index (BMI), sporting activity and type, mechanism of injury (MOI), chronicity of symptoms, PTSA, and the ISI. Descriptive and quantitative statistics were used.

resultsSeventy-five patients (88 knees) with OSD were studied (28 boys, 47 girls). The average age was 12.2 years and the average BMI was 22.3. The mechanism of injury (MOI) included repetitive stress (77%) and trauma (23%). The duration of knee pain averaged 10.3 months. Sixty-six patients were included in the nonoperative cohort. Nine patients were included in the operative cohort and underwent surgery due to persistent symptoms after skeletal maturity with tubercleplasty and/or ossicle excision. The average PTSA was 12.1° ± 1.7° and average ISI was 1.05 ± 0.15. Comparing the operative and nonoperative patients, we found no significant difference in PTSA (11.2° ± 0.73° versus 12.8° ± 1.8°, p < 0.064). However, we did find that patients treated operatively had a lower ISI (0.95 ± 0.18 versus 1.14 ± 0.13, p < 0.001).

conclusionIn patients with OSD, operative and nonoperative patients demonstrated a similar PTSA. On the other hand, the ISI was higher in nonoperative patients. In the current paper, a decreased ISI was helpful in predicting the need for operative intervention in symptomatic patients after skeletal maturity.
