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

Purpose: The two most common types of anterior knee pain (AKP) in adolescents are patellofemoral pain (PFP) and Osgood-Schlatter disease (OSD). Accurate diagnosis is essential to guide treatment, but can be challenging due to overlapping clinical features of these two conditions. Infrared thermography (IRT) offers a noninvasive method to detect physiological differences such as local inflammation or altered perfusion. The aim of this exploratory study was to evaluate whether IRT can detect distinct thermal profiles in adolescents with unilateral PFP or OSD and explore its potential as a supplementary diagnostic tool. Methods: This within-subject study included 28 adolescents with unilateral AKP (17 with PFP, 11 with OSD) who underwent infrared thermography. Mean skin temperatures were recorded for both symptomatic and contralateral knees, and side-to-side differences were calculated for each participant. These individual asymmetries were then summarised descriptively within each diagnostic group and compared between groups. Results: In the OSD group, symptomatic knees exhibited higher skin temperatures than contralateral knees (mean ΔT = +0.48 ± 0.47°C 95% confidence interval [CI]: 0.16-0.80), whereas in the PFP group, symptomatic knees showed lower temperatures (mean ΔT = -0.78 ± 90°C, 95% CI: -1.25 to -0.32). The between-group contrast corresponded to a large standardised mean difference (Hedges' Conclusion: Infrared thermography revealed contrasting thermal asymmetries in adolescents with PFP or OSD. These preliminary findings suggest that IRT may help characterise distinct thermal patterns associated with AKP. Level of Evidence: Level III.
