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

Objectives: To describe the force-time characteristics of HVLA hip manipulation (HVLA-HM) with (DP) and without (NDP) a drop-piece. Methods: Twenty asymptomatic participants (22-28 years; 60% female) received 3 whip HVLA-HM (DP) on one hip and 3 whip HVLA-HM (NDP) on the other. Force-time characteristics were collected using Force-Sensing Table Technology (FSTT®) and analyzed descriptively. Results: On average, HVLA-HM (DP) had a 1st peak force initiation of 40N (±19), peak force of 637N (±218), time to 1st peak of 62ms (±26), loading rate of 10763N/s (±5042) and 2nd peak force of 197N (±85). HVLA-HM (NDP) had a 1st peak force initiation of 36N (±23), peak force of 567N (±290), time to 1st peak of 63ms (±22), loading rate of 9465N/s (±5966) and 2nd peak force of 197N (±82). Conclusion: Forces during these techniques present with slightly higher peak forces and loading rates during HVLA-HM (DP) at the patient-table interface.
