Arthroscopic subacromial decompression versus placebo surgery for subacromial pain syndrome: 10 year follow-up of the FIMPACT randomised, placebo surgery controlled trial.
Trial report in BMJ (Clinical research ed.), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT00428870 (Arthroscopic Decompression Versus Diagnostic Arthroscopy Without Subacromial Decompression Versus Supervised Exercise Therapy in Treatment of Subacromial Impingement Syndrome. A Blinded Randomized Controlled Trail.), which is not on this map. Not yet cited in PubMed.
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.

Abstract
objectiveTo assess the long term efficacy of arthroscopic subacromial decompression (ASD) versus placebo surgery (diagnostic arthroscopy) and exercise therapy in patients with subacromial pain syndrome.
designRandomised, placebo surgery controlled trial.
settingOrthopaedic department of three public hospitals in Finland.
participants210 adults aged 35 to 65 years with symptoms consistent with subacromial pain syndrome for more than three months, enrolled from 1 February 2005 with 10 year follow-up to 20 September 2023. Participants and outcome assessors were blinded to group allocation in the primary (ASD versus placebo surgery) comparison.
interventionsASD, placebo surgery, and exercise therapy (1:1:1). Exercise therapy was used as a pragmatic comparator.
main outcome measuresThe primary outcomes were shoulder pain at rest and on arm activity, both assessed at 10 years using a visual analogue scale (VAS, ranging from 0 to 100, with 0 denoting no pain). The minimally important difference was defined as 15. A mixed model repeated measures analysis of variance was used, treating participants as random factors, incorporating baseline values as covariates.
resultsParticipants were randomly assigned to ASD (n=59), placebo surgery (n=63), and exercise therapy (n=71). Of these, a total of 168 participants (87%) completed the 10 year follow-up. In the primary intention-to-treat analysis (ASD versus placebo surgery), no between group differences were observed for the two primary outcomes at 10 years: the mean difference between groups (ASD minus placebo surgery) was -1.5 points (95% confidence interval (CI) -8.6 to 5.6) in VAS pain score at rest and -3.2 points (-13.0 to 6.5) in VAS pain score on arm activity. No significant between group differences were found for any of the secondary outcomes or adverse events. In the pragmatic comparison, the mean difference between groups (ASD minus exercise therapy) was -4.0 points (-11.0 to 3.0) in VAS pain score at rest and -9.4 points (-19.0 to 0.3) in VAS pain score on arm activity. No significant between group differences were observed for the secondary outcomes or adverse events.
conclusionIn patients with subacromial pain syndrome, ASD offered no benefit over placebo surgery or exercise therapy during 10 year follow-up.
