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
Introduction: Lateral epicondylitis is a common cause of lateral elbow pain that impairs grip strength and daily activities. While corticosteroid injection offers rapid symptom relief, dry needling is a newer, minimally invasive technique that may enhance tendon healing and provide longer-lasting benefits. This study compared the short- and long-term efficacy of corticosteroid injection and dry needling in improving pain and function in patients with lateral epicondylitis. Methods: This prospective comparative observational study was conducted in the Department of Orthopedics, Shree Birendra Hospital, Kathmandu, from June 2022 to July 2023 after obtaining ethical approval from the Institutional Review Committee (Registration number: 492). Sixty-two patients aged I860 years with clinically diagnosed lateral epicondylitis were consecutively assigned to receive either corticosteroid injection (n = 31) or dry needling (n = 31). Pain and function were assessed using the Patient-Rated Tennis Elbow Evaluation questionnaire at baseline, 3 weeks, and 3 months. Intergroup comparisons were made using t-tests or Mann-Whitney U tests, and intragroup differences were analyzed with paired t-tests or Wilcoxon signed-rank tests. Results: Baseline characteristics were comparable. Corticosteroid injection produced greater short-term improvement at 3 weeks (pain 28.23 ± 10.27 vs 41.71 ± 8.93, p < 0.001), while dry needling showed superior outcomes at 3 months (Patient-Rated Tennis Elbow Evaluation 42.97 ± 16.32 vs 50.45 ± 15.33, p = 0.04). Both interventions achieved significant within-group improvement (p < 0.001). Conclusions: Corticosteroid injection offers faster initial pain relief, but dry needling yields better long-term functional recovery. Both are effective modalities, with dry needling preferred for sustained management of lateral epicondylitis.
