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

This study investigated the acute physiological and performance responses to a simulated prolonged service game designed to replicate the most demanding phases of competitive tennis. Fourteen nationally ranked male players (17.8 ± 0.9 y) performed 12 consecutive maximal intensity serves, each immediately followed by eight alternating forehands and backhands. Internal load was monitored before, during and after the protocol using heart rate, oxygen uptake and venous blood samples (ammonia, creatine kinase, albumin, sodium, calcium, lactate and glucose). External load was quantified with a Doppler radar gun to measure ball speed and high-frame-rate video to assess serve precision. Statistical significance was set at
