Effect of muscle strengthening on perceived pain and static knee angles in young subjects with patellofemoral pain syndrome.
Article in Journal of exercise rehabilitation, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
The purpose of this pilot study was to determine the effects of strength training of the knee muscles on perceived pain and static knee angles in young subjects with patellofemoral pain syndrome (PFPS). Ten patients, 100% female (mean age, 18.2±3.8 years), with unilateral PFPS (anterior knee pain for at least 3 months), received muscle strengthening of the hip and knee (10 sessions over a period of 3 weeks). The outcome measures were perceived pain (visual analogue scale, VAS) and static knee angles (knee rotation measurer). All measures were collected at pre-, postintervention, and at 1-month follow-up (VAS). Muscle strengthening reduced perceived pain after intervention in 90.8% in subjects and this result was maintained at 1-month follow-up (all,
