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: A randomized, double-blind, placebo-controlled cross-over study was conducted to investigate the efficacy and safety of E-PR-01, a proprietary formula containing Patients and Methods: Forty adults aged 20-60 years with self-reported pain score of ≤30 mm at rest and ≥60 mm post-exertion on a 100-mm visual analog scale (VAS) were randomized in a 1:1 ratio to receive either the E-PR-01 (200 mg twice daily) or placebo for 5 days. The primary outcome was time to achieve meaningful pain relief (MPR) (≥40% reduction in post-exertion pain VAS score from baseline) post-single dose of intervention on day 1 compared to placebo. The secondary outcomes were post-exertion pain intensity difference (PID) at 2-, 3- and 4-hours and time-weighted sum of pain intensity difference (SPID) over 4 hours post single dose on day 1; post-exertion VAS score at 4 hours' post-intervention on day 5; percentage of responders on day 1; and physical efficiency as assessed by the total duration of exercise sessions completed after single dose of IP compared to placebo. Results: The average time to achieve MPR was 3.38 hours, 32.50% of participants achieved it in the E-PR-01 group post single-dose administration on day 1 as opposed to the placebo where no participant achieved MPR. There were significant intergroup differences in PID (-23.58 vs 2.45 mm) and SPID (-67.48 vs -0.08 mm) at 4 hours of E-PR-01 and placebo administration on day 1. 95% of participants in the IP group experienced some degree of pain relief within 2 hours compared to 37.5% in the placebo group. Conclusion: A single dose of E-PR-01 provided a statistically significant as well as clinically meaningful reduction in exercise-induced knee joint discomfort within 4 hours of administration.
