Evaluation of efficacy of Valsalva for attenuating needle puncture pain in first time nonremunerated voluntary plateletpheresis donors: A prospective, randomized controlled trial.

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
backgroundPlateletpheresis is generally safe but may have adverse reactions. Adverse reactions can negatively influence donor recruitment and retention. Valsalva is a proven method of attenuating pain caused by venipuncture.
aimsThe aim was to evaluate the efficacy of the Valsalva maneuver on the attenuation of needle pain and donor anxiety. SETTINGS AND
designThis prospective randomized controlled trial was conducted between November 2015 and April 2016 at the Department of Transfusion Medicine. SUBJECTS AND
methodsOne-hundred and sixty consecutive donors were grouped into control group (C) and Valsalva group (V) each of sample size 80. The Valsalva group performed a Valsalva maneuver and control did nothing before the venipuncture. Anxiety and pain were scored using a 10 cm visual analog scale (VAS). Severity was graded as VAS = 0 defines no pain and anxiety, VAS = 1-3 as mild pain and anxiety, VAS = 4-6 as moderate pain and anxiety, VAS = 7-9 as severe pain and anxiety, whereas VAS = 10 denotes extreme pain and anxiety. STATISTICAL ANALYSIS: Statistical Package for Social Sciences, version 23 was used for analysis. Independent samples
resultsIn the Valsalva group, post-Valsalva anxiety levels were significantly reduced to (1 [0-2]) from their pre-Valsalva values of (2 [0-3]); (
conclusionsValsalva reduced both severity of venipuncture pain and anxiety. Valsalva can be performed by donors as it is an easy, painless, and nonpharmacological method of pain and anxiety attenuation.
